Question

qual é o numero que,mutiplicado por 4/9 é igual a 8?​

Answer 1

x.4/9 = 8

x = 8.9/4

x = 8:2.9/4:2

x = 9.2

x = 18

Answer 2

Resposta:

$x. \frac{4}{9} = 8$

$\frac{4}{9} x = 8$

$\frac{9}{4} . \frac{4}{9} x = \frac{9}{4} .8$

$\frac{9 \div 9}{4} . \frac{4}{9 \div 9} x = \frac{9}{4} .8$

$\frac{1}{4} . \frac{4}{1} x = \frac{9}{4} .8$

$\frac{1}{4} .4x = \frac{9}{4} = 8$

$\frac{9}{4 \div 4} . \frac{4 \div 4}{9} x = \frac{9}{4} .8$

$\frac{9}{1} . \frac{1}{9} x = \frac{9}{4} .8$

$x = \frac{9}{4} .8$

$x = \frac{9}{4 \div 4} .8 \div 4$

$x = \frac{9}{1} .2$

$x = 9.2$

$x = 18$
