The number of homes in a housing development increased from 25 to 30. What was the percent of increase?

Question

i dont get math!

Answer 1

20%

Answer 2

So 30 - 25 = 5

So then you divide 5 into 25 --  25/5 = 5

Then to find the actual percentage divide 5 into 100    100/5 = 20

So it would be 20% increase

Answer 3

Increase of 5 homes.

5/25 = .2

.2 = 20%

Answer 4

30-25=5

5/30=.1667

16.67%

Answer 5

100 * (30-25) / 25 = 100 * 5 / 25 = 100/5 = +20 %

Stright method:

30/25 = 1.2 = +20%
