71.25 is what percent of 79 - 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 79 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 79, so we can write it down as 100%=79.
4. We know, that x% equals 71.25 of the output value, so we can write it down as x%=71.25.
5. Now we have two simple equations:
1) 100%=79
2) x%=71.25
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%=79/71.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 71.25 is what percent of 79

100%/x%=79/71.25
(100/x)*x=(79/71.25)*x       - we multiply both sides of the equation by x
100=1.1087719298246*x       - we divide both sides of the equation by (1.1087719298246) to get x
100/1.1087719298246=x
90.189873417722=x
x=90.189873417722

now we have:
71.25 is 90.189873417722% of 79
