Question

I need help with this.

Answer 1

`\left( \cfrac{1}{~~ ( 5 )/( 4 ) ~~} \right)(-20)\left( \cfrac{6}{~~ -( 1 )/( 3 ) ~~} \right)\implies \left( \cfrac{(1)/(1)}{~~ ( 5 )/( 4 ) ~~} \right)(-20)\left( \cfrac{(6)/(1)}{~~ ( -1 )/( 3 ) ~~} \right) \\\\\\ \left( \cfrac{1}{1}\cdot \cfrac{4}{5} \right)(-20)\left( \cfrac{6}{1}\cdot \cfrac{3}{-1} \right)\implies \left( \cfrac{4}{5} \right)(-20)\left( -18 \right)\implies \cfrac{4(-20)(-18)}{5} \\\\\\ \cfrac{1440}{5}\implies \text{\LARGE 288}`
