87 is what percent of 734 - 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 734 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 734, so we can write it down as 100%=734.
4. We know, that x% equals 87 of the output value, so we can write it down as x%=87.
5. Now we have two simple equations:
1) 100%=734
2) x%=87
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%=734/87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 87 is what percent of 734

100%/x%=734/87
(100/x)*x=(734/87)*x       - we multiply both sides of the equation by x
100=8.4367816091954*x       - we divide both sides of the equation by (8.4367816091954) to get x
100/8.4367816091954=x
11.852861035422=x
x=11.852861035422

now we have:
87 is 11.852861035422% of 734
