Question

24) Using appropriate property find
215 × (-3/7) - 1/14 - 3/7 * 3/5​

Answer 1

Answer:

$215 \times \frac{ - 3}{7} - \frac{1}{4} - \frac{3}{7} \times \frac{3}{5}$

$\frac{ - 645}{7} - \frac{1}{4} - \frac{9}{35}$

• Taking lcm = 70

$\frac{ - 6450 - 5 - 18}{70}$

$\frac{ - 6473}{70}$

$92.47$
