Question

5- Determine o valor de x nas proporções: x/6 = 32/48 b) 1/7 - × - 6/49
​

Answer 1

Resposta:

a) x=4

b) x=13

Explicação passo a passo:

  $\frac{x}{6} = \frac{32}{48} \\\\\ \frac{x}{6} = \frac{2}{3} \\\\\x= \frac{2}{3} . 6 \\\\\x= \frac{12}{3} \\\\\x=4$

$\frac{1}{7} = \frac{x-6}{49} \\\\\ \frac{1}{7}.49=x-6 \\\\\ \frac{49}{7} = x-6\\\\\7=x-6\\\\\x-6=7\\\\\x=7+6\\\\\x=13$
