Question

2/3 de uma turma corresponde ha 40 alunos.Quantos alunos ha nessa turma?

Answer 1

$\frac{2}{3} = 40 \\ \\ \frac{2}{3} = \frac{40}{1} \\ \\ \frac{120}{2} = 60$

Answer 2

40-------2/3
X--------3/3



$\frac{2}{3} x = 40 \times \frac{3}{3} \\ \\ \frac{2}{3} x = 40 \times 1 \\ \\ \frac{2}{3} x = 40 \\ \\ x = \frac{40}{ \frac{2}{3} } \\ \\ x = 40 \times \frac{3}{2} \\ \\ x = \frac{120}{2} \\ \\ x = 60$




Logo, essa turma tem 60 alunos. ok
