Question

Which is greater: 25% of 15 or 15% of 25? Explain your reasoning using mathematical evidence or visual models

Answer 1

15% of 25

Explanation:

Given the following questions:

25% of 15
15% of 25

We find the answer by using the formula to calculate percentage for both questions.

Question one:

`(p* n)/(100)`

`(25*15)/(100) =25*15=375/100=3.75`

`=3.75`

25% of 15 is 3.75

Question two:

`(p* n)/(100)`

`(15* 25)/(100)=15*25=375/100=3.75`

`=3.75`

15% of 25 is 3.75

Finally:

`3.75=3.75`

`15-3.75=11.25`

`25-3.75=21.25`

`11.25 < 21.25`

Which means 15% of 25 is "greater than" 25% of 15.

Hope this helps.
