Question

13. Simply each of the following by using suitable property. Also name the property (a) 1 / 5 × 2/ 15 – 1 /5 × 2/ 5

Answer 1

$\frac{1}{5} \times \frac{2}{15} - \frac{1}{5} \times \frac{2}{5} \\ \\ \frac{1}{5} \bigg( \frac{2}{15 } - \frac{2}{5} \bigg) \\ \\ \frac{1}{5} \bigg( \frac{2 - 6}{15} \bigg) \\ \\ \frac{1}{5} \times \frac{ - 4}{15} = \red{\frac{ - 4}{75} }$
