\(\dfrac{35}{91}=\dfrac{5}{13}\)

\(\dfrac{37}{111}=\dfrac{1}{3}\)

\(\dfrac{119}{153}=\dfrac{7}{9}\)

\(\dfrac{322}{345}=\dfrac{14}{15}\)

\(\dfrac{35}{91}=\dfrac{5}{13}\)

\(\dfrac{37}{111}=\dfrac{1}{3}\)

\(\dfrac{119}{153}=\dfrac{7}{9}\)

\(\dfrac{322}{345}=\dfrac{14}{15}\)

119/153=7/9

     \(\frac{6.9-2.17}{63.3-119}\)

\(\Rightarrow\frac{54-34}{189-119}\)

\(\Rightarrow\frac{20}{70}\)

51/68 = 51:17/68:17 = 3/4

Chúc bạn học tốt!! ^^

\(\dfrac{3}{4}\) nhé

\(\dfrac{51}{68}=\dfrac{51:17}{68:17}=\dfrac{3}{4}\)

+ Rút gọn phân số:

+ Quy đồng mẫu số 

MSC = 13.7 = 91.

\(\dfrac{3}{4}\)

\(\dfrac{51}{68}=\dfrac{3}{4}\)

3/4

-51/34 = -3/2

Hok tốt !

\(\frac{-51}{34}=\frac{-51:17}{34:17}=\frac{-3}{2}\)

TL:

Ta có: \(\frac{-51}{34}=\frac{-51:17}{34:17}=\frac{-51}{34}\)

Vậy\(-\frac{51}{34}=-\frac{51:17}{34:17}=-\frac{3}{2}\)

CHÚC BẠN HỌC TỐT NHÉ.
