What is 87.221 percent of 52 - 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 52 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 52 is 100%, so we can write it down as 52=100%.
4. We know, that x is 87.221% of the output value, so we can write it down as x=87.221%.
5. Now we have two simple equations:
1) 52=100%
2) x=87.221%
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:
52/x=100%/87.221%
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 87.221% of 52

52/x=100/87.221
(52/x)*x=(100/87.221)*x       - we multiply both sides of the equation by x
52=1.1465128810722*x       - we divide both sides of the equation by (1.1465128810722) to get x
52/1.1465128810722=x
45.35492=x
x=45.35492

now we have:
87.221% of 52=45.35492
