&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;MEDIDAS DE COMPRIMENTO


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

O&nbsp;metro&nbsp;é a unidade fundamental das medidas de&nbsp;

comprimento. O seu&nbsp;símbolo e&nbsp;m.




MÚLTIPLOS E SUBMÚLTIPLOS DO METRO





&nbsp; &nbsp; &nbsp; &nbsp; Para medir grandes distâncias, utilizando os&nbsp;múltiplos do metro.&nbsp;



&nbsp; &nbsp; &nbsp; &nbsp; São eles:



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; O&nbsp;quilômetro, cujo símbolo é&nbsp;km. &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;1 km&nbsp;=&nbsp;1.000 m



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; O&nbsp;hectômetro, cujo símbolo é&nbsp;hm&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; . &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;1 hm =&nbsp;100 m&nbsp;



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; O&nbsp;decâmetro, cujo símbolo é&nbsp;dam. &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;1 dam&nbsp;=&nbsp;10 m


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Dessas unidades, a mais utilizada é o quilômetro.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Para medir pequenos comprimentos utilizamos os&nbsp;submúltiplos do&nbsp;



&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;metro. São eles:



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; O&nbsp;decímetro, cujo símbolo é&nbsp;dm.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; O decímetro é a décima parte do metro.&nbsp;&nbsp;



&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;1 dm = 1/10 m =&nbsp;0,1 m



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; O&nbsp;centímetro, cujo símbolo é&nbsp;cm.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; O centímetro é a centésima parte do metro.&nbsp;&nbsp;



&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;1 cm&nbsp;= 1/100 m =&nbsp;0,01 m



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; O&nbsp;milímetro, cujo símbolo é&nbsp;mm.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; O milímetro é a milésima parte do metro.&nbsp;



&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;1&nbsp;mm&nbsp;= 1/1.000&nbsp;m&nbsp;=&nbsp;0,001&nbsp;m




&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Dessas unidades, as mais utilizadas são o centímetro e o milímetro.

LEITURA DAS MEDIDAS DE COMPRIMENTO



&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; A leitura das medidas de comprimento pode ser efetuada com o



&nbsp; auxílio do quadro de unidades. Por exemplo, para ler a medida&nbsp;



&nbsp; 12,45&nbsp;m,&nbsp;podemos&nbsp; :

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;

&nbsp; 1º) representar o quadro de unidades;



&nbsp; 2º) colocar o número no quadro de unidades, localizando o último&nbsp;



&nbsp; algarismo da parte&nbsp;inteira&nbsp;&nbsp;sob a respectiva unidade;


&nbsp; 3º) ler a&nbsp;parte inteira&nbsp;acompanhada da unidade de medida do seu

&nbsp;último algarismo e aparte decimal&nbsp;acompanhada da unidade de&nbsp;

medida do seu último algarismo.&nbsp;&nbsp; &nbsp;

TRANSFORMAÇÃO DE UNIDADES






&nbsp; &nbsp;As transformações de unidade de comprimento baseiam-se no seguinte fato:




Cada unidade de comprimento é 10 vezes maior que a unidade imediatamente inferior.




&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

Podemos transformar uma unidade maior em uma unidade menor, acrescentando zero(s) ou deslocando a vírgula para a direita.

MEDIDAS DE MASSA

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Muitas vezes precisamos saber quanto “pesam” as pessoas, os&nbsp;

animais ou os objetos. Para isso utilizamos as unidades de massa.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; O&nbsp;grama&nbsp;é a unidade básica de medida de massa: Símbolo&nbsp;g.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; O&nbsp;quilograma&nbsp;(kg) e o&nbsp;grama&nbsp;(g) são as unidades mais usadas&nbsp;



para medir a massa de um corpo.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Para medir pequenas massa utilizamos o&nbsp;miligrama&nbsp;(mg) O&nbsp;



miligrama é usado principalmente nas embalagens de produtos



&nbsp;químicos e farmacêuticos.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Para medir grandes massas utilizamos a&nbsp;tonelada&nbsp;(t). Uma&nbsp;



tonelada corresponde a&nbsp;1.000 kg.





1 t = 1.000 kg

a)&nbsp;1 kg&nbsp;= _____ g&nbsp; &nbsp; &nbsp; &nbsp;c)&nbsp;1 g&nbsp;= _____ mg&nbsp; &nbsp; &nbsp;&nbsp;e) 1 dag = _____ g

b) 1 cg = _____ g&nbsp; &nbsp; &nbsp; &nbsp;d) 1 mg = _____ g&nbsp; &nbsp; &nbsp;&nbsp;f) 1 t = _____ kg




4.&nbsp;Complete as frases com mg, g, kg ou t. Use a unidade de massa mais adequada:


a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;O peso da criança era 32 _____.

b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Aquele navio pesa 97 _____.

d)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cada comprimido pesa 8 _____.




5. Quantos quilogramas existem em&nbsp;½&nbsp;t ? _______________.




6.&nbsp;Um elefante pesa cerca de 5,2 toneladas. Represente essa massa em quilogramas.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Resposta: O elefante pesa cerca de _______________ kg.




7. Um quilograma de ferro para construção custa R$ 15,00. Quanto custarão 3 t desse ferro?


&nbsp; &nbsp; &nbsp; &nbsp;Resposta: Três toneladas custarão ____________________.&nbsp;




LEITURA DAS MEDIDAS DE MASSA



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A leitura das medidas de massa segue o mesmo procedimento que é aplicado às medidas de comprimento.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Veja


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;†&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Vamos ler a medida&nbsp;6,075 kg.

TRANSFORMAÇÃO DE UNIDADES



A transformações são efetuadas de modo idêntico ao das&nbsp;transformações das medidas de comprimento.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Não esqueça:



CADA UNIDADE DE MASSA É 10 VEZES MAIOR


QUE A UNIDADE IMEDIATAMENTE INFERIOR.

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;

Exemplos:



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;†&nbsp; &nbsp; &nbsp;&nbsp;&nbsp; Vamos transformar&nbsp;7,5&nbsp;kg&nbsp;em&nbsp;g.
