$\frac{18}{27}$ + $\frac{4}{19}$ + $\frac{1}{3}$ = $\frac{342}{513}$ + $\frac{108}{513}$ + $\frac{171}{513}$ = $\frac{23}{19}$ a, x – $\frac{2}{65}$ = $\frac{4}{39}$ x = $\frac{4}{39}$ + $\frac{2}{65}$ x = $\frac{2}{15}$. Vậy x = $\frac{2}{15}$. b,$\frac{1}{115}$ – x = $\frac{-4}{25}$ x = $\frac{1}{115}$ – $\frac{-4}{25}$ x = $\frac{97}{575}$. Vậy x = $\frac{97}{575}$. Bình luận
$\frac{18}{27}+\frac{4}{19}+\frac{1}{3}$
$=\frac{2}{3}+\frac{1}{3}+\frac{4}{19}$
$=1+\frac{4}{19}$
$=\frac{23}{19}$
$a)$
$x-\frac{2}{65}=\frac{4}{39}$
$x=\frac{4}{39}+\frac{2}{65}$
$x=\frac{260}{2535}+\frac{78}{2535}$
$x=\frac{338}{2535}$
$b)$
$⇒x=\frac{4}{39}+\frac{2}{65}$
$⇒x=\frac{338}{2535}$
$\frac{18}{27}$ + $\frac{4}{19}$ + $\frac{1}{3}$
= $\frac{342}{513}$ + $\frac{108}{513}$ + $\frac{171}{513}$
= $\frac{23}{19}$
a, x – $\frac{2}{65}$ = $\frac{4}{39}$
x = $\frac{4}{39}$ + $\frac{2}{65}$
x = $\frac{2}{15}$.
Vậy x = $\frac{2}{15}$.
b,$\frac{1}{115}$ – x = $\frac{-4}{25}$
x = $\frac{1}{115}$ – $\frac{-4}{25}$
x = $\frac{97}{575}$.
Vậy x = $\frac{97}{575}$.
