What is 90.88 percent of 87 - 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 87 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 87 is 100%, so we can write it down as 87=100%.
4. We know, that x is 90.88% of the output value, so we can write it down as x=90.88%.
5. Now we have two simple equations:
1) 87=100%
2) x=90.88%
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:
87/x=100%/90.88%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 90.88% of 87

87/x=100/90.88
(87/x)*x=(100/90.88)*x       - we multiply both sides of the equation by x
87=1.1003521126761*x       - we divide both sides of the equation by (1.1003521126761) to get x
87/1.1003521126761=x
79.0656=x
x=79.0656

now we have:
90.88% of 87=79.0656
