50.3 is what percent of 72 - 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 72 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 72, so we can write it down as 100%=72.
4. We know, that x% equals 50.3 of the output value, so we can write it down as x%=50.3.
5. Now we have two simple equations:
1) 100%=72
2) x%=50.3
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%=72/50.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 50.3 is what percent of 72

100%/x%=72/50.3
(100/x)*x=(72/50.3)*x       - we multiply both sides of the equation by x
100=1.4314115308151*x       - we divide both sides of the equation by (1.4314115308151) to get x
100/1.4314115308151=x
69.861111111111=x
x=69.861111111111

now we have:
50.3 is 69.861111111111% of 72
