75.9 is what percent of 79.9 - 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 79.9 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 79.9, so we can write it down as 100%=79.9.
4. We know, that x% equals 75.9 of the output value, so we can write it down as x%=75.9.
5. Now we have two simple equations:
1) 100%=79.9
2) x%=75.9
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%=79.9/75.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 75.9 is what percent of 79.9

100%/x%=79.9/75.9
(100/x)*x=(79.9/75.9)*x       - we multiply both sides of the equation by x
100=1.0527009222661*x       - we divide both sides of the equation by (1.0527009222661) to get x
100/1.0527009222661=x
94.993742177722=x
x=94.993742177722

now we have:
75.9 is 94.993742177722% of 79.9
