Question

CHuyển hỗn số về phân số 3 5/9 4 7/12 5 3/10 8 13/40

Answer 1

\(3\dfrac{5}{9}=\dfrac{3\times9+5}{9}=\dfrac{32}{9}\\ 4\dfrac{7}{12}=\dfrac{4\times12+7}{12}=\dfrac{55}{12}\\ 5\dfrac{3}{10}=\dfrac{5\times10+3}{10}=\dfrac{53}{10}\\ 8\dfrac{13}{40}=\dfrac{8\times40+13}{40}=\dfrac{323}{40}\)

Answer 2

3 5/9 = 32/9

4 7/12 = 55/12

5 3/10 = 53/10

8 13/40 = 333/40

Answer 3

\(3\dfrac{5}{9}=\dfrac{32}{9}\)

\(4\dfrac{7}{12}=\dfrac{66}{12}\)

\(5\dfrac{3}{10}=\dfrac{53}{10}\)

\(8\dfrac{13}{40}=\dfrac{333}{40}\)

Answer 4

\(3\dfrac{5}{9}=\dfrac{3.9+5}{9}=\dfrac{32}{9}\)

\(4\dfrac{7}{12}=\dfrac{4.12+7}{12}=\dfrac{55}{12}\)

\(5\dfrac{3}{10}=\dfrac{5.10+3}{10}=\dfrac{53}{10}\)

\(8\dfrac{13}{40}=\dfrac{8.40+13}{40}=\dfrac{343}{40}\)
