Question

Determine o valor de x nas proporções

a) x/5 = 2/6

b) x+4/125 = 2/25

Answer 1

Resposta:

$a) x = \frac{10}{6}$

$b) x = 6$

Explicação passo a passo:

$a) \frac{x}{5} = \frac{2}{6} \\\\\frac{x}{5}.5 = \frac{2}{6}.5 \\\\\\\ x = \frac{10}{6}$

$b) \frac{x+4}{125} = \frac{2}{25} \\\\\frac{x+4}{125}.125 = \frac{2}{25}.125\\\\x + 4 = 250/25\\\\x + 4 = 10\\\\x = 10 - 4\\\\x = 6$
