Question

74/4x=6,8/29 com resposta completa

Answer 1

Resposta:

$x=\frac{5365}{68}$

Explicação passo-a-passo:

$\frac{74}{4x} =\frac{6,8}{29}\\ 4x\times6,8=74\times29\\27,2x=2146\\x=\frac{2146}{27,2}\\\\x=\frac{2146}{\frac{136}{5} } \\\\x=\frac{5365}{68}$

Obs:

$27,2=\frac{272^{\div2}}{10} =\frac{136}{5}$

Obs 2:

$\frac{2146}{\frac{136}{5} } =\frac{2146}{1} \times\frac{5}{136} =\frac{10730^{\div2}}{136} =\frac{5365}{68}$
