987.5 is what percent of 1300 - 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 1300 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 1300, so we can write it down as 100%=1300.
4. We know, that x% equals 987.5 of the output value, so we can write it down as x%=987.5.
5. Now we have two simple equations:
1) 100%=1300
2) x%=987.5
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%=1300/987.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 987.5 is what percent of 1300

100%/x%=1300/987.5
(100/x)*x=(1300/987.5)*x       - we multiply both sides of the equation by x
100=1.3164556962025*x       - we divide both sides of the equation by (1.3164556962025) to get x
100/1.3164556962025=x
75.961538461538=x
x=75.961538461538

now we have:
987.5 is 75.961538461538% of 1300
