A resposta é 36 pq 100 × 36 = 3600 ÷ 100 = 36 , e a outra é 100 pq 400 × 25 = 10000 ÷ 100 = 100.

100 ----------------- 100 %
   x ------------------  36%

100x = 36.100
100x = 3600
x = 3600/100
x = 36

36% de 100 = 36

400 ------------- 100 %
    x -------------   25 %

100x = 400.25
100x = 10000
x = 10000 / 100
x = 100

25% de 400 = 100
