Question

hola cómo resuelvo 8*(e : 10)=20

Answer 1

Respuesta:

$8 \times (e \div 10) = 20 \\ 8 \times ( \frac{1}{10} e) = 20 \\ \\ \frac{8}{10}e = 20 \\ \\ \frac{4}{5} e = 20 \\ e = 20 \div \frac{4}{5} \\ \\ e = \frac{100}{4} \\ \\ e = 25 \\ comprobación \\ 8 \times (25 \div 10) = 20 \\ 8 \times \frac{25}{10} = 20 \\ \\ \frac{200}{10} = 20 \\ \\ 20 = 20$
