Ta có:
\(\frac{301}{70}\)= \(\frac{43}{10}\)
\(\frac{17}{34}=\frac{1}{2}\), \(\frac{60}{70}=\frac{6}{7}\),\(\frac{126}{255}=\frac{42}{85}\),\(\frac{24}{72}=\frac{1}{3}\), \(\frac{105}{30}=\frac{7}{2}\), \(\frac{78}{56}=\frac{39}{28}\)
\(\frac{1}{2},\frac{6}{7},\frac{42}{85},\frac{1}{3},\frac{7}{2},\frac{39}{28}\)

a . 21/70 = 3/10 ; 56/96 = 7/12 ; 60/72 = 15/18
Mình chỉ làm tới đây thôi .
\(\frac{70}{45}=\frac{70\div5}{45\div5}=\frac{14}{9}\)
\(\frac{18}{54}=\frac{18\div18}{54\div18}=\frac{1}{3}\)
Chú ý : Dấu này \(\div\) là dấu chia nha
6/8 = 3/4 ; 39/65 = 3/5 ; 70/42 = 5/3 ; 84/231 = 4/11 ; 117117/504504 = 13/56 ; 7/35 = 1/5 ; 112/140 = 4/5 ; 165/110 = 3/2 ; 30/105 = 2/7 ; 153153/414414 = 17/46
\(\frac{12}{30}=\frac{2}{5}\)
\(\frac{20}{45}=\frac{4}{9}\)
\(\frac{28}{70}=\frac{2}{5}\)
\(\frac{34}{51}=\frac{2}{3}\)
\(\frac{12}{30}\)= \(\frac{12:6}{30:6}\)= \(\frac{2}{5}\)
\(\frac{20}{45}\)=\(\frac{20:5}{45:5}\)=\(\frac{4}{9}\)
\(\frac{28}{70}\)=\(\frac{28:7}{70:7}\)=\(\frac{4}{10}\)=\(\frac{4:2}{10:2}\)=\(\frac{2}{5}\)
\(\frac{34}{51}\)=\(\frac{34:14}{51:14}\)=\(\frac{34:17}{51:17}\)= \(\frac{2}{3}\)
\(\dfrac{70}{74}\) = \(\dfrac{35}{37}\)
\(\dfrac{70}{74}=\dfrac{35\cdot2}{37\cdot2}=\dfrac{35}{37}\)
