Question

Chuyển các hỗn số sau thành phân số :

\(2\frac{2}{4}\);           \(5\frac{1}{10}\);             \(1\frac{1}{2}\)

Answer 1

\(2\frac{2}{4}=\frac{2.4+2}{4}=\frac{10}{4}\)

\(5\frac{1}{10}=\frac{5.10+1}{10}=\frac{51}{10}\)

\(1\frac{1}{2}=\frac{1.2+1}{2}=\frac{3}{2}\)

Answer 2

\(2\frac{2}{4}=\frac{10}{4}\) ;   \(5\frac{1}{10}=\frac{51}{10}\) ;       \(1\frac{1}{2}=\frac{3}{2}\)

Answer 3

\(2\frac{2}{4}=\frac{2.4+2}{4}=\frac{10}{4}=\frac{5}{2}\)

\(5\frac{1}{10}=\frac{5.10+1}{10}=\frac{51}{10}\)

\(1\frac{1}{2}=\frac{1.2+1}{2}=\frac{3}{2}\)
