Answer:

Let's say the number is 100, if it decreases by 50% it would be 50. Then if it decreases again by 50% then it would be 25. Hope this helps!

Answer:

0.75a

Explanation:

You want the result of a number 'a' being decreased by 50%, then increased by 50%.

Multiplier

The multiplier of the number is (1 + %change).

a(1 -50%) = 0.50a . . . . . . decreased by 50%

(0.50a)(1 +50%) = 0.75a . . . . . then increased by 50%

The result of the two changes by 50% is 0.75a.
