15.2 is what percent of 17.3 - 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 17.3 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 17.3, so we can write it down as 100%=17.3.
4. We know, that x% equals 15.2 of the output value, so we can write it down as x%=15.2.
5. Now we have two simple equations:
1) 100%=17.3
2) x%=15.2
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%=17.3/15.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.2 is what percent of 17.3

100%/x%=17.3/15.2
(100/x)*x=(17.3/15.2)*x       - we multiply both sides of the equation by x
100=1.1381578947368*x       - we divide both sides of the equation by (1.1381578947368) to get x
100/1.1381578947368=x
87.861271676301=x
x=87.861271676301

now we have:
15.2 is 87.861271676301% of 17.3
