Answer 1

Resposta:

D. ( x ) 2,75 ou $\frac{11}{4}$

Explicação passo a passo:

$\frac{1,5}{0,3} -\frac{\frac{3}{2} }{\frac{2}{3} }$

$\frac{1,5\times \frac{2}{2} }{0,3 \times \frac{10}{10}} -\frac{\frac{3}{2} }{\frac{2}{3} }$

$\frac{ \frac{1,5\times2}{2} }{\frac{0,3 \times 10}{10}} -\frac{\frac{3}{2} }{\frac{2}{3} }$

$\frac{\frac{3}{2} }{\frac{3}{10} } -\frac{\frac{3}{2} }{\frac{2}{3} }$

$\frac{3}{2}\div\frac{3}{10} -\frac{3}{2}\div\frac{2}{3}$

$\frac{3}{2}\times\frac{10}{3} -\frac{3}{2}\times\frac{3}{2}$

$\frac{3\times10}{2\times3} -\frac{3\times3}{2\times2}$

$\frac{30}{6} -\frac{9}{4}$

$5 -\frac{9}{4}$

$5\times\frac{4}{4} -\frac{9}{4}$

$\frac{5\times4}{4} -\frac{9}{4}$

$\frac{20}{4} -\frac{9}{4}$

$\frac{20-9}{4}$

$\frac{11}{4}$

D. ( x ) 2,75 ou $\frac{11}{4}$
