Question

Renata pagou 5 reais por 2 bombons quantos custao 4 desses bobons ? E se ele comprasse 8?

Answer 1

5,00----- 2
x ---------4
2x = 20,00
x = 10,00



Se 4 bombons = 10
então 8 bombons = 10 x 2 = 20,00

Answer 2

$\frac{2}{4}= \frac{5}{x} \\\\ 2*x=4*5\\\\ 2x=20\\\\ x= \frac{20}{2}\\\\ x=10$

$\frac{2}{8}= \frac{5}{x} \\\\ 2*x=8*5\\\\ 2x=40\\\\ x= \frac{40}{2}\\\\ x=20$
