Question

Percent decrease from 28 seconds to 23

Answer 1

28 - 23 = 5
Then you do 28 divided by 5. The reason why I chose 28 was because it's the original number. You always divide your answer to the original number. So 28 divided by 5.

So this equals 5.6. So the percentage decrease is 5.6%

Answer 2

.18%
28-23= 5
5 divided by 28= .1785
round to nearest tenth to find your percentage
