Question

Ajuda no exercício?

Se 7/6 do saldo bancário de João equivalem a 21 000 reais, quantos reais equivaleriam a 2/3 do saldo?

Answer 1

7/6 ------------------- 21000 reais
2/3 -------------------- x 

7/6x = 21000 . 2/3
7/6x = 42000/3
7/6x = 14000
x = 14000 : 7/6
x = 12000

2/3 equivalem a 12 000 reais 

Answer 2

$\frac{7}{6}$ =  R$21000 reais

$\frac{2}{3}$ = x 

7/6x = 21000 × 2/3
7/6x = 42000/3
7/6x = 14000
x = 14000 ÷ 7/6
x = 12000

2/3 =  R$12 000 reais
