Question

Tìm phân số tối giản a/b

2/3 - a/b + 1/4 = 1/6

 

Answer 1

\(\frac{2}{3}\)-\(\frac{a}{b}\)+\(\frac{1}{4}\)=\(\frac{1}{6}\)

\(\frac{2}{3}\)-\(\frac{a}{b}\)            =\(\frac{1}{6}\)-\(\frac{1}{4}\)

\(\frac{2}{3}\)-\(\frac{a}{b}\)            =\(-\frac{1}{12}\)

                       \(\frac{a}{b}\)=\(\frac{2}{3}\)-\(-\frac{1}{12}\)

                         \(\frac{a}{b}\)=\(\frac{3}{4}\)

Vay \(\frac{a}{b}\)=\(\frac{3}{4}\)

Answer 2

\(\frac{2}{3}+\frac{a}{b}+\frac{1}{4}=\frac{1}{6}\)

\(\frac{a}{b}=\frac{1}{6}-\frac{1}{4}-\frac{2}{3}=\frac{-3}{4}\)

k mk nha

Answer 3

\(\frac{2}{3}-\frac{a}{b}+\frac{1}{4}=\frac{1}{6}\Rightarrow\frac{a}{b}=\frac{2}{3}-\frac{1}{6}+\frac{1}{4}\Rightarrow\frac{a}{b}=\frac{3}{4}\)
