72.8 is what percent of 1500 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 1500 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 1500, so we can write it down as 100%=1500.
4. We know, that x% equals 72.8 of the output value, so we can write it down as x%=72.8.
5. Now we have two simple equations:
1) 100%=1500
2) x%=72.8
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=1500/72.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 72.8 is what percent of 1500

100%/x%=1500/72.8
(100/x)*x=(1500/72.8)*x       - we multiply both sides of the equation by x
100=20.604395604396*x       - we divide both sides of the equation by (20.604395604396) to get x
100/20.604395604396=x
4.8533333333333=x
x=4.8533333333333

now we have:
72.8 is 4.8533333333333% of 1500
