Question

de 58 bombons ja comi 75% quantos bombons mim restam?

Answer 1

Faz regra de 3 simples:
58----------100%
x------------75%

100x= 4350
 x= 4350/100
x= 43,5

58-43,5= 14,5

Resposta: Te restam 14,5 bombons.

Answer 2

58/x = 100/75; 58/x = 4/3; 4x = 58.3; 4x = 174; x= 174/4; x = 43,5. Como deu 43,5: 58-43,5 = 14,5 bombons; Resp.: 14,5 bombons que restam.
