Answer 2

Ta có :

\(\frac{1}{3}< \frac{3}{4}\)

\(\frac{15}{17}=\frac{1515}{1717}\)

\(\frac{9}{10}< \frac{10}{11}\)

Answer 3

5/6 < 6/5 vì 5/6 < 1 và 6/5 > 1

1/3 <3/4 (quy đồng mẫu số) 1/3=4/12   ;    3/4=9/12

15/17=1515/1717 (rút gọn phân số) 1515/1717=15/17

9/10 10/11(quy đồng mẫu số)  9/10=99/110   ;  10/11=100/110
