Question

porfavor necesito el resultado de este ejercicio 7/9:4/3+8/12.2/5

Answer 1

$\frac{7}{9} \div \frac{4}{3} + \frac{8}{12} \times \frac{2}{5}$

$\frac{7}{9} \times\frac{3}{4} + \frac{8}{12} \times \frac{2}{5}$

$\frac{7}{9} \times\frac{3}{4} + \frac{8}{6} \times \frac{1}{5}$

$\frac{7}{3}\times\frac{1}{4} + \frac{8}{6} \times \frac{1}{5}$

$\frac{7}{3}\times\frac{1}{4} + \frac{4}{3} \times \frac{1}{5}$

$\frac{7}{12} + \frac{4}{3} \times \frac{1}{5}$

$\frac{7}{12} + \frac{4}{15}$

$\frac{35+16}{60}$

$\frac{51}{60}$

$\frac{17}{20}$

Respuesta: 17/20.

Answer 2

$Procedimiento:$

$\frac{7}{9} : \frac{4}{3} + \frac{8}{12} . \frac{2}{5} =$

$\frac{7.3}{9.4} + \frac{8.2}{12.5} =$

$\frac{21}{36} + \frac{16}{60} =$

$\frac{180:36.21+180:60.16}{180} =$

$\frac{105+48}{180} =$

$\frac{153}{180} = \frac{17}{20}$
