12. \( 1 \frac{24}{25} \times 1 \frac{3}{25}= \)

To calculate \( 1 \frac{24}{25} \times 1 \frac{3}{25} \), follow these steps: 1. **Convert Mixed Numbers to Improper Fractions:** \[ 1 \frac{24}{25} = \frac{25 + 24}{25} = \frac{49}{25} \] \[ 1 \frac{3}{25} = \frac{25 + 3}{25} = \frac{28}{25} \] 2. **Multiply the Improper Fractions:** \[ \frac{49}{25} \times \frac{28}{25} = \frac{49 \times 28}{25 \times 25} = \frac{1372}{625} \] 3. **Convert the Improper Fraction Back to a Mixed Number:** \[ \frac{1372}{625} = 2 \frac{122}{625} \] (Since \( 625 \times 2 = 1250 \) and \( 1372 - 1250 = 122 \).) 4. **Simplify if Possible:** The fraction \( \frac{122}{625} \) cannot be simplified further as 122 and 625 have no common factors other than 1. **Final Answer:** \[ 1 \frac{24}{25} \times 1 \frac{3}{25} = 2 \frac{122}{625} \]
