Question

2/5 + 4/3 x 3/5 - (-1/4)²​

Answer 1

Explicación paso a paso:

$=\frac{2}{5}+\frac{4}{3}\times \frac{3}{5}-\left(-\frac{1}{4}\right)^2$

$=\frac{2}{5}+\frac{4}{5}-\frac{1}{4^2}$

$=\frac{6}{5}-\frac{1}{4^2}$

$=\frac{96}{80}-\frac{5}{80}$

$\mathrm{Ya\:que\:los\:denominadores\:son\:iguales,\:combinar\:las\:fracciones}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}$

$=\frac{96-5}{80}$

$=\frac{91}{80}$
