Question

using appropriate properties , find
3/5 ×1/2-5/7+1/2×3/7
​

Answer 1

Answer:

$\frac{3}{5} \times \frac{1}{2} - \frac{5}{7} + \frac{1}{2} \times \frac{3}{7}$

$= > \frac{3}{10} - \frac{5}{7} + \frac{3}{14}$

$= > \frac{3}{10} - \frac{10 + 3}{14}$

$= > \frac{3}{10} - \frac{13}{14}$

$= > \frac{21 - 65}{70}$

$= > - \frac{44}{14}$

$= > - \frac{22}{7}$
