Bài 1: Rút gọn phân số:
125/150                  5/25
15/120                    36/48
64/720                    414141/494949
171171/180180

                                                                                

Answer 1

`125/150 = 5/6`.

`5/25 = 1/5`

`15/120 = 1/8`

`36/48 = 3/4`

`64/720 = 8/90`

`414141/494949 = 41/49`

`171171/180180 = 171/180 = 19/20`

Answer 2

\(\dfrac{125}{150}=\dfrac{5}{6}\)

\(\dfrac{15}{120}=\dfrac{1}{8}\)

\(\dfrac{64}{720}=\dfrac{4}{45}\)

\(\dfrac{171171}{180180}=\dfrac{19}{20}\)

\(\dfrac{5}{25}=\dfrac{1}{5}\)

\(\dfrac{36}{48}=\dfrac{3}{4}\)

\(\dfrac{414141}{494949}=\dfrac{41}{49}\)

Answer 3

125/150 = 5/6

15/120 = 1/8

64/720 = 4/45

5/25 = 1/5

36/48 = 3/4

414141/494949 = 41/49

171171/180180 = 19/20
