a) \(\left(\frac{1}{3}+\frac{1}{5}\right)\times x=\frac{8}{25}\)
\(\frac{8}{15}\times x=\frac{8}{25}\)
\(x=\frac{8}{25}:\frac{8}{15}\)
\(x=\frac{3}{5}\)
Vậy x = 3/5
b) \(\frac{1}{2}:\frac{4}{5}:x=\frac{7}{3}\)
\(\frac{5}{8}:x=\frac{7}{3}\)
\(x=\frac{5}{8}:\frac{7}{3}\)
\(x=\frac{15}{56}\)
Vậy x = 15/36
ủng hộ tớ nha. thank you nhìu
a) (1/3 + 1/5) . x = 8/25
(5/15 + 3/15) . x = 8/25
=> 8/15 . x = 8/25
x = 8/25 : 8/15
x = 3/5
Vậy x = 3/5
uh. nhớ nhé
a) (\(\frac{1}{3}\)+ \(\frac{1}{5}\)) x X=\(\frac{8}{25}\)
\(\frac{8}{15}\)x X = \(\frac{8}{25}\)
X= \(\frac{8}{25}\): \(\frac{8}{15}\)
X= \(\frac{3}{5}\)
b)\(\frac{1}{2}\):\(\frac{4}{5}\)x X = \(\frac{7}{3}\)
\(\frac{5}{8}\)x X = \(\frac{7}{3}\)
X= \(\frac{7}{3}\): \(\frac{5}{8}\)
x= \(\frac{56}{15}\)
k mình nha bạn
b) 1/2 : 4/5 : x = 7/3
5/8 : x = 7/3
x = 5/8 : 7/3
x = 15/56
Vậy x = 15/56
