Thanks, How do i find the percent notation of a fraction?

14 over 25

Answer 3

Divide: 14 by 25.

Then multiply by 100 because percent means the number out of 100.

Or you can just move the decimal point two places to the right to get the percentage.

How do I solve for N?

2/10 = n/15

Answer 5

You could set this up as a proportion and cross multiply.

2/10 = n/15
2*15 = 10n
30 = 10n
3 = n

Answer 6

SO the answear would be 2/10 = 30/15
because 2*15= 30

Answer 7

Bryan -- I showed you how to solve this problem.

2/10 = n/15
2*15 = 10n
30 = 10n <<Divide both sides of the equation by 10.

3 = n
