53 is what percent of 128.979 - 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 128.979 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 128.979, so we can write it down as 100%=128.979.
4. We know, that x% equals 53 of the output value, so we can write it down as x%=53.
5. Now we have two simple equations:
1) 100%=128.979
2) x%=53
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%=128.979/53
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 53 is what percent of 128.979

100%/x%=128.979/53
(100/x)*x=(128.979/53)*x       - we multiply both sides of the equation by x
100=2.4335660377358*x       - we divide both sides of the equation by (2.4335660377358) to get x
100/2.4335660377358=x
41.091960706782=x
x=41.091960706782

now we have:
53 is 41.091960706782% of 128.979
