Question

Evaluate $\frac{5\times (-144)\times (-27)}{(-15)\times \left(18\right)\times (-16)}$

• A. $\frac{9}{4}$
• B. $\frac{9}{8}$
• C. $\frac{9}{2}$
• D. $\frac{-9}{2}$

Answer 1

The correct option is C $\frac{9}{2}$

As there are $2$ negative numbers in the numerator and $2$ in the denominator, the answer will be positive.
Canceling out the common factors and simplifying we get
$\frac{5\times (-144)\times (-27)}{-\left(15\right)\times 18\times (-16)}=\frac{9\times 27}{3\times 18}=\frac{9}{2}$
