Question

3/2.4/5-x=2/3

X nhân 3 một phần3 =3 một phần3: 4 một phần 4

Answer 1

\(\frac{3}{2}.\frac{4}{5}-x=\frac{2}{3}\)

\(\frac{6}{5}-x=\frac{2}{3}\)

\(x=\frac{6}{5}-\frac{2}{3}\)

\(x=\frac{18}{15}-\frac{10}{15}\)

\(x=\frac{8}{15}\)

Answer 2

\(\frac{3}{2}\times\frac{4}{5}-x=\frac{2}{3}\)

\(\frac{12}{10}-x=\frac{2}{3}\)

\(\frac{6}{5}-x=\frac{2}{3}\)

\(x=\frac{6}{5}-\frac{2}{3}\)

\(x=\frac{18}{15}-\frac{10}{15}\)

\(x=\frac{8}{15}\)

\(x\times3\frac{1}{3}=\frac{3}{3}:4\frac{1}{4}\)

\(x\times\frac{10}{3}=1:\frac{17}{4}\)

\(x\times\frac{10}{3}=1.\frac{4}{17}\)

\(x\times\frac{10}{3}=\frac{4}{17}\)

\(x=\frac{4}{17}:\frac{10}{3}\)

\(x=\frac{4}{17}\times\frac{3}{10}\)

\(x=\frac{6}{85}\)
