Question

Write 129/13 as a mixed number.

Answer 1

To convert the improper fraction \( \frac{129}{13} \) into a mixed number, you can follow these steps:

1. **Divide the numerator by the denominator**:
\[
129 \div 13 = 9 \quad \text{(this is the whole number part)}
\]

2. **Calculate the remainder**:
\[
129 - (13 \times 9) = 129 - 117 = 12 \quad \text{(this is the remainder)}
\]

3. **Write it as a mixed number**:
The mixed number will be the whole number part plus the remainder over the original denominator:
\[
9 \frac{12}{13}
\]

So, \( \frac{129}{13} \) as a mixed number is \( 9 \frac{12}{13} \).
