What is 66.35 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 66.35% of the output value, so we can write it down as x=66.35%.
5. Now we have two simple equations:
1) 87=100%
2) x=66.35%
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%/66.35%
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 66.35% of 87

87/x=100/66.35
(87/x)*x=(100/66.35)*x       - we multiply both sides of the equation by x
87=1.5071590052751*x       - we divide both sides of the equation by (1.5071590052751) to get x
87/1.5071590052751=x
57.7245=x
x=57.7245

now we have:
66.35% of 87=57.7245
