Question

Rút gọn phân số sau :
\(\frac{2929-101}{2.1919+404}\)

Answer 1

\(\frac{2929-101}{2.1919+404}\)

\(=\frac{101.\left(29-1\right)}{101\left(2.19+4\right)}\)

\(=\frac{28}{38+4}\)

\(=\frac{28}{42}\)

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

Answer 2

Ta có : 

\(\frac{2929-101}{2.1919+404}\)

\(=\frac{29.101-101}{2.19.101+4.101}=\frac{101\left(29-1\right)}{101\left(2.19+4\right)}=\frac{28}{38+4}=\frac{28}{42}=\frac{2}{3}\)

Ủng hộ mk nha !!! ^_^

Answer 3

dễ ma bạn

Answer 4

\(\frac{2929-101}{2.1919+404}\)

\(=\frac{101.\left(29-1\right)}{101.\left(2.19+4\right)}\)

\(=\frac{29-1}{2.19+4}\)

\(=\frac{28}{42}\)
