Question

The value of (– 24r2 s) ÷ (– 8r s) is​

Answer 1

Answer:

The ratio of Maths, English and Science books = 5 : 12 : 7

Sum of the ratios = 5+12+7=24

The number of Science books = 140

Let the the total number of books be X.

Therefore, 7/ 24 *X = 140

X = 140 * 24/7 = 20 * 24 = 480

The number of English books=12/24 * 480

= 240

Answer 2

Answer:

The value of the given equation is,  $\frac{-24r^{2}s }{-8rs}$ = $3r$

Step-by-step explanation:

Given : $\frac{-24r^{2}s }{-8rs}$

To find : The final value of this above equation.

Solution :

• The given equation is,  $\frac{-24r^{2}s }{-8rs}$
• In order to solve this given equation, we have take common from numerator and denominator. We get

   $\frac{-24r^{2}s }{-8rs}$ $=\frac{3r}{1}$

• ∴  $\frac{-24r^{2}s }{-8rs}$ $= 3r$
• ∴ The value of the given equation is,  $\frac{-24r^{2}s }{-8rs}$ = $3r$
