Question

calcular (5/4 -2/3)÷(-7/3 +3/4) (5/4 ∙ 8/15)^(-4)=

Answer 1

$( \frac{5}{4} - \frac{2}{3} ) \div ( \frac{7}{3} + \frac{3}{4} )( \frac{5}{4} \times \frac{8}{15} ) ^{ - 4}$

$\frac{7}{12} \div \frac{37}{12} \times ( \frac{2}{3} ) ^{ - 4}$

$\frac{7}{12} \times \frac{12}{37} \times ( \frac{3}{2} ) ^{4}$

$7 \times \frac{1}{37} \times \frac{81}{16}$

$\frac{ \red5 \: \red6 \: \red7}{ \red5 \: \red9 \: \red2}$
