Toán $\frac{2}{3}\times \frac{2}{5}-\frac{4}{7}\times \frac{2}{5}=$ ??? 06/09/2021 By Rose $\frac{2}{3}\times \frac{2}{5}-\frac{4}{7}\times \frac{2}{5}=$ ???
$\frac{2}{3}$ × $\frac{2}{5}$ – $\frac{4}{7}$ × $\frac{2}{5}$ = ($\frac{2}{3}$ – $\frac{4}{7}$) × $\frac{2}{5}$ = $\frac{2}{21}$ × $\frac{2}{5}$ = $\frac{4}{105}$ Trả lời
2/3 x 2/5 – 4/7 x 2/5
= 4/15 – 8/35
= 4/105

$\frac{2}{3}$ × $\frac{2}{5}$ – $\frac{4}{7}$ × $\frac{2}{5}$
= ($\frac{2}{3}$ – $\frac{4}{7}$) × $\frac{2}{5}$
= $\frac{2}{21}$ × $\frac{2}{5}$
= $\frac{4}{105}$
