Answer 1

Propiedades:

Division de fracciones:

$\frac{a}{b} \div\frac{c}{d}$ = $\frac{a}{b} x \frac{d}{c}$

Multiplicacion de fracciones:

$\frac{a}{b} .\frac{c}{d}$ = $\frac{a.c}{b.d}$

Resta de fracciones:

$\frac{a}{b} -\frac{c}{d}$ = $\frac{a.d - b.c}{b.d}$

Solucion:

= $\frac{5}{3} -[\frac{9}{10} \div(\frac{7}{5} .\frac{1}{2})]$

= $\frac{5}{3} -[\frac{9}{10} \div(\frac{7.1}{5.2})]$

= $\frac{5}{3} -[\frac{9}{10} \div(\frac{7}{10} )]$

= $\frac{5}{3} -[\frac{9}{10} . \frac{10}{7} ]$

= $\frac{5}{3} -[\frac{9.10}{10.7}]$

= $\frac{5}{3} -[\frac{90}{70} ]$

= $\frac{5}{3} -\frac{9}{7}$

= $\frac{5.7-9.3}{3.7}$

= $\frac{35 - 27}{21}$

= $\frac{8}{21}$
