X/N  = P --> X is P percent of N

15/N = 0.05 ---> N = 15/0.05 = 300

15 is 5% of 300

Let the number be represented by x.

15=5% of x

15 =5x/100

multiply both sides by 100

1500 =5x  (100 cancels 100 on the right hand side)

divide both sides by 5

300 = x.

(If you check back your answer into the equation )

5 % 0f 300 =15

`5/100=15/x`

`5x=1500`

`x=300`

To find this we can use the equation

15/x = 5/100 first multiply 5 with " x " and 100 with 15 

By multiplying you should get

5x = 1500 now divide both sides by 5

By dividing, you should get

x = 300  which is your answer
