128.99 is what percent of 959 - 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 959 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 959, so we can write it down as 100%=959.
4. We know, that x% equals 128.99 of the output value, so we can write it down as x%=128.99.
5. Now we have two simple equations:
1) 100%=959
2) x%=128.99
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%=959/128.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 128.99 is what percent of 959

100%/x%=959/128.99
(100/x)*x=(959/128.99)*x       - we multiply both sides of the equation by x
100=7.4346848592914*x       - we divide both sides of the equation by (7.4346848592914) to get x
100/7.4346848592914=x
13.45046923879=x
x=13.45046923879

now we have:
128.99 is 13.45046923879% of 959
