Em Matemática, existem símbolos que podem ser usados para tornar mais rápida a escrita. Por exemplo, se quisermos escrever “nove é maior que cinco”, podemos registrar assim:9 &gt; 5
Do mesmo modo, se quisermos escrever “cinco é menor que nove”, podemos registrar assim:5 &lt; 9
Complete os espaços de modo a tornar verdadeira as sentenças matemáticas:

      231 &lt; ____      352 &gt; ____      145 &gt; ____      458 &lt;_____  
      ____&lt; 300      ____&gt; 893      ____ &lt; 983      ____&gt; 800  


Fazendo leituras de outros númerosAlguns municípios do Brasil possuíam, em 2010, pouco mais que mil habitantes.Na tabela abaixo leia as informações e diga qual é o menos populoso deles:

      André da Rocha (RS)      1216  
      Araguainha (MT)      1095  
      Cedro do Abaeté   (MG)      1212  
      Miguel Leão (PI)      1253  
      Nova Castilho (SP)      1127  
      Oliveira de Fátima   (TO)      1035  

Agora escreva com algarismos
a) vinte mil, cento e dois:b) trinta e cinco mil e dez:c) duzentos mil e duzentos:d) três milhões:e) quarenta milhões:f) quinhentos milhões:
Ligue cada número à forma como deve ser lido:
