\(\dfrac{3}{7}:x=\dfrac{5}{7}\)

      \(x=\dfrac{3}{7}:\dfrac{5}{7}\)

     \(x=\dfrac{3}{7}\times\dfrac{7}{5}\)

     \(x=\dfrac{21}{35}\) 

     \(x=\dfrac{3}{5}\)

\(\dfrac{3}{7}:x=\dfrac{5}{7}\\ x=\dfrac{3}{7}:\dfrac{5}{7}\\ x=\dfrac{3}{5}\)

Vậy `x=3/5`

`@An`

\(\frac{7}{15}+\frac{2}{10}=\frac{14}{30}+\frac{6}{30}=\frac{20}{30}=\frac{2}{3}\)

\(\frac{8}{3}+\frac{4}{3}=\frac{12}{3}=\frac{4}{1}=4\)

a, \(\frac{7}{15}+\frac{2}{10}=\frac{2}{3}\)

b,\(\frac{8}{3}+\frac{4}{3}=4\)

\(\frac{7}{15}\)\(+\frac{2}{10}\)\(=\frac{2}{3}\)

\(\frac{8}{3}\)\(+\frac{4}{3}\)\(=4\)

\(\frac{7}{15}+\frac{2}{10}\)

\(=\frac{7}{15}+\frac{1}{5}\)

=\(\frac{7}{15}+\frac{3}{15}\)

=\(\frac{10}{15}\)

=\(\frac{2}{3}\)

\(\frac{7}{15}+\frac{2}{10}\)

\(=\frac{7}{15}+\frac{1}{5}\)

\(=\frac{7}{15}+\frac{3}{15}\)

\(=\frac{10}{15}=\frac{2}{3}\)

\(\frac{7}{5}+\frac{2}{10}=\frac{70}{50}+\frac{10}{50}=\frac{80}{50}=\frac{8}{5}\)\(\frac{8}{5}\)

\(\dfrac{8}{9}:\dfrac{4}{3}=\dfrac{8}{9}\times\dfrac{3}{4}=\dfrac{24}{36}=\dfrac{2}{3}\)

\(\frac{2}{3}\)bạn nhé! Nếu cần thì mình sẽ cho bạn cách làm

bang 2/3

bằng 2/3 bạn nhé cho mik nha

\(1,\left(5\right)=1+0,\left(5\right)=1+0,\left(1\right).5=1+\frac{1}{9}.5=\frac{9}{9}+\frac{5}{9}=\frac{14}{9}\)

\(\frac{6}{7}:\frac{3}{2}\)

\(=\frac{6}{7}\times\frac{2}{3}\)

\(=\frac{12}{21}\)

\(=\frac{4}{7}\)

6/7:3/2=6/7x2/3

          =18/21

          =6/7

Ko cần k cho mink đâu kb vs mink nhé

6/7 : 3/2 = 4/7

Nhớ k cho mik nhé
