Question

Simplify: – -3/5 x (-10/9) x (21/-4) x (-6)

Q.2. If 23% of a number is 46, find the number






answer these in easy words

Answer 1

(1).

$\frac{-3}{5} * \frac{-10}{9} * \frac{21}{-4} * (- 6)$

$-6 * \frac{3}{5} * \frac{10}{9} * ( \frac{-21}{4} )$

$\frac{3 * 10 * 21 * 6}{5 * 9 * 4}$

$\frac{3780}{180}$

21.



(2) Let the number be x.

Given that 23% of a number is 46.

23/100 * x = 46

x = 46 * 100/23

   = 200.


Therefore the number = 200.


Hope this helps!
