Question

Tính

7/8:2

9/11:3

6:3/7

14:21/5

Answer 1

7/8:2=7/8*1/2=7/16

9/11:3=9/11*1/3=9/33=3/11

6:3/7=6/1*7/3=42/3=14

14:21/5=14/1*5/21==70/21

Answer 2

\(\frac{7}{8}:2=\frac{7}{8}.\frac{1}{2}=\frac{7}{16}\)

\(\frac{9}{11}:3=\frac{9}{11}.\frac{1}{3}=\frac{9}{33}=\frac{3}{11}\)

\(6:\frac{3}{7}=6.\frac{7}{3}=14\)

\(14:\frac{21}{5}=14.\frac{5}{21}=\frac{70}{21}\)
