`2424/4545=(2424:303)/(4545:303)=8/15`

= 8/15 

Nhớ tick nha

4545/3535=4545:505/3535:505=9/7

2323/6767=2323:101/6767:101=23/67

HT

\(\frac{4545}{3535}=\frac{9}{7}\)

\(\frac{6767}{2323}=\frac{67}{23}\)

rút gọn thành 9/7 và 23/67 nha.

2323/4545 = 2323 : 101/4545:101=23/45

đều chia cho 101 nhé

2323:101=23

4545:101=45

phân số còn:23/45

\(\frac{2323}{4545}\)=\(\frac{2323:101}{4545:101}\)=\(\frac{23}{45}\)

Kb vc mk nha !

=15/31

\(\dfrac{-1515}{-3131}=\dfrac{\left(-1515\right):\left(-101\right)}{\left(-3131\right):\left(-101\right)}=\dfrac{15}{31}\)

chi tiết nhá

31/35

31/35

`4242/3132=(4242:101)/(3131:101)=42/31`

\(\dfrac{4242}{3131}=\dfrac{4242:101}{3131:101}=\dfrac{42}{31}\)

\(\dfrac{4242}{3131}\)\(=\dfrac{4242:101}{3131:101}=\dfrac{42}{31}\)

Ta có: \(\frac{3131}{3535}=\frac{31}{35}\)

ssssssssssssssssssssssssssssssssssssssssss

\(\frac{3131}{3535}\)= \(\frac{31}{35}\)

Tk cho mình nhé !
