Question

12 phần 17 chia 4

12 chia 6 phần 13

9 chia 3 phần 5 nhân 4 phẫn 15

 

Answer 1

12/17 chia 4 = 3/17

12 chia 6/13=26

9 chia 3/5*4/15=4

Answer 2

\(\frac{12}{17}:4=\frac{12}{17}.\frac{1}{4}=\frac{3}{17}.\frac{1}{1}=\frac{3}{17}\)

\(12:\frac{6}{13}=12.\frac{13}{6}=2.\frac{13}{1}=26\)

\(9:\frac{3}{5}.\frac{4}{15}=9.\frac{5}{3}.\frac{4}{15}=3.\frac{5}{1}.\frac{4}{15}=\frac{15}{1}.\frac{4}{15}=\frac{1}{1}.\frac{4}{1}=4\)
