Question

Chuyển hỗn số thành phân số: 2\(\frac{1}{3}\), 4\(\frac{2}{5}\), 3\(\frac{1}{4}\), 9\(\frac{5}{7}\), 10\(\frac{3}{10}\) 

Answer 1

a)7/3

b)22/5

13/4

68/7

103/10

Answer 2

\(2\frac{1}{3}=\frac{7}{3};4\frac{2}{5}=\frac{22}{5};3\frac{1}{4}=\frac{13}{4};9\frac{5}{7}=\frac{68}{7};10\frac{3}{10}=\frac{103}{10}\)

Answer 3

\(2\frac{1}{3}=\frac{7}{3}\)

\(4\frac{2}{5}=\frac{22}{5}\)

\(3\frac{1}{4}=\frac{13}{4}\)

\(9\frac{5}{7}=\frac{68}{7}\)

\(10\frac{3}{10}=\frac{103}{10}\)

Answer 4

a]7/3

b]22/5

13/4

68]7
