segundos





4) Transforme em
minutos, observando o exemplo resolvido:



Exemplo &nbsp;= 2º 17´ = 2 x 60´ + 17´ = 137´



a) 5º 7´ =&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;b) 3º 20´ =

c) 10º 35´ =&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;d) 12º 18´ = &nbsp; &nbsp;&nbsp;

e) 3º 45´ = &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;f) 5º 54´ = &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;

g) 7º 12´ = &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;h) 9º 36´ =



5) Transforme:



Exemplo: 120´= 120 :
60 = 2º ===== resolvidos&nbsp;&nbsp;==== 120" = 120" : 60 = 2´



a) 180´em graus =&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;b) 240´em graus =

c) 300´ em graus =&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;d) 360´em
graus&nbsp; =

e) 180" em
minutos =&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; f) 240" em
minutos =

g) 300" em
minutos =&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;h) 360" em
minutos =



6) Transforme em
graus e minutos:



Exemplo :&nbsp;75´= 1º 15´&nbsp;&nbsp;(obs divida os minutos por 60 para obter os
graus. O resto , se existir, serão os minutos.)



a) 90´ =&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;b) 95´=
