Question

5） \frac{25}{10} = \underline{\quad\quad}
8） \frac{31}{5} = \underline{\quad\quad}
11） \frac{7}{3} = \underline{\quad\quad}
14） \frac{31}{4} = \underline{\quad\quad}

Explanation:

Step1: Simplify $\frac{25}{10}$

Divide numerator and denominator by 5: $\frac{25\div5}{10\div5}=\frac{5}{2}=2\frac{1}{2}$

Step2: Simplify $\frac{31}{5}$

Divide 31 by 5: $31\div5 = 6$ with remainder 1, so $\frac{31}{5}=6\frac{1}{5}$

Step3: Simplify $\frac{7}{3}$

Divide 7 by 3: $7\div3 = 2$ with remainder 1, so $\frac{7}{3}=2\frac{1}{3}$

Step4: Simplify $\frac{31}{4}$

Divide 31 by 4: $31\div4 = 7$ with remainder 3, so $\frac{31}{4}=7\frac{3}{4}$

Answer:

1. $2\frac{1}{2}$ (or $\frac{5}{2}$)
2. $6\frac{1}{5}$ (or $\frac{31}{5}$)
3. $2\frac{1}{3}$ (or $\frac{7}{3}$)
4. $7\frac{3}{4}$ (or $\frac{31}{4}$)
