$\frac{4}{15}$ – x = $\frac{-16}{25}$.$\frac{5}{64}$
$\frac{4}{15}$ – x = $\frac{-80}{1600}$
$\frac{4}{15}$ – x = $\frac{-1}{20}$
x = $\frac{4}{15}$ – $\frac{-1}{20}$
x = $\frac{16}{60}$ – $\frac{-3}{60}$
x = $\frac{16 – (-3)}{60}$
x = $\frac{19}{60}$
Đáp án:
$\dfrac{4}{15} – x = – \dfrac{16}{25} . \dfrac{5}{64}$

$ => \dfrac{4}{15} – x = \dfrac{-1}{20}$
$ $
$=> x = \dfrac{4}{15} – \dfrac{-1}{20}$
