Question

25% dos 40% de 1000g, representa quanto em gramas? Calcule.

Answer 1

Basta fazer o seguinte cálculo :

$\dfrac{100}{40} =\dfrac{1000}{X} \\\\\\ 100X = 40\cdot1000 \\\\\\ 100X = 40000 \\\\\\ X =\dfrac{40000}{1000} \\\\\\ X = 400$

===========================

25% = 1/4

400 ÷ 4 = 100


Resposta : 100
