Question

Simplify:
$(-5\times (2/15\left)\right)-(-6\times (2/9\left)\right)$

Answer 1

(i) Given $(-5\times (2/15\left)\right)-(-6\times (2/9\left)\right)$
$(-5\times (2/15\left)\right)-(-6\times (2/9\left)\right)=(-10/15)-(-12/9)$
$=(-2/3)+\left(12/9\right)$
$=(-6/9)+\left(12/9\right)$
$=\left(6/9\right)$
$=2/3$
