ko biết

bạn có phân số nào bé hơn ko gửi đi mik làm co ahihi

\(\frac{1212}{1313}=\frac{12}{13}\)

\(\frac{201201}{202202}=\frac{201}{202}\)

Câu c: \(\dfrac{121}{121}\)

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

= 8/15 

Nhớ tick nha

12/13

\(\dfrac{1212}{1313}=\dfrac{1212:101}{1313:101}=\dfrac{12}{13}\)

= \(\dfrac{12}{13}\)

1212/1515 = 4/5

363636/545454 = 2/3

~hok tốt~

#Trang#

a)1212/1515=4/5.Cả tử và mẫu chia cho 303

b)363636/545454=2/3.Cả tử và mẫu chia cho 181818

\(a,\frac{1212}{1515}=\frac{12.101}{15.101}=\frac{12}{15}\)

\(b,\frac{363636}{545454}=\frac{36.10101}{54.10101}=\frac{36}{54}\)
