7.2 is what percent of 43 - 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 43 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 43, so we can write it down as 100%=43.
4. We know, that x% equals 7.2 of the output value, so we can write it down as x%=7.2.
5. Now we have two simple equations:
1) 100%=43
2) x%=7.2
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%=43/7.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.2 is what percent of 43

100%/x%=43/7.2
(100/x)*x=(43/7.2)*x       - we multiply both sides of the equation by x
100=5.9722222222222*x       - we divide both sides of the equation by (5.9722222222222) to get x
100/5.9722222222222=x
16.744186046512=x
x=16.744186046512

now we have:
7.2 is 16.744186046512% of 43
