Question

What percent of 75 is 15? I need a full explanation thanks!

Answer 1

1) step 1 the way you calculate this is by dividing the number in question by the number which comes after the "of"

So:

x percent of y is:


`(x)/(y)`

a percent of b is:


`(a)/(b)`


and for us:

x percent of y is:


`(15)/(75)`

we can also simplify it:



`(1)/(5)`

for this i divided both numbers by 15.

2) for the second step you multiply the fraction by 100%, ,which is 1: you can always multiply by 1!



`(1)/(5)*100%`=20%

because 100/5=20


was is clear? let me know if you have more questions!
