Question

If'a' is increased by 25% and 'b' is decreased by 25% then the resulting number will be equal. What is the ratio
of a to b?​

Answer 1

Answer:

a:b = 3:5.

Step-by-step explanation:

a + 0.25a = b - 0.25b

1.25a = 0.75b       Divide both sides by b:

1.25a / b = 0.75  Now divide both sides by 1.25

a/b = 0.75/1.25

a/b= 3/5.
