Question

$\frac{ - 15}{4} \times ( \frac{3}{7 } + \frac{ - 12}{5}) = ( \frac{ - 15}{4} \times \frac{3}{7} ) + ( \frac{ - 15}{4} \times \frac{ - 12}{5} )$
​

Answer 1

$= > - \frac{15}{4} \times ( \frac{3}{7} + \frac{ - 12}{5} ) = ( - \frac{15}{4} \times \frac{3}{7} ) + ( - \frac{15}{4} \times \frac{ - 12}{5} ) \\ \\ = > - \frac{15}{4} \times \frac{15 - 84}{35} = - \frac{45}{28} + 9 \\ \\ = > - \frac{15}{4} \times \frac{ - 69}{35} = \frac{ - 45 + 252}{28} \\ \\ = > - \frac{3}{4} \times \frac{ - 69}{7} = \frac{207}{28} \\ \\ = > \frac{207}{28} = \frac{207}{28} = 1$

hope it helps ☺️⬆️
