87.5 is what percent of 446 - 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 446 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 446, so we can write it down as 100%=446.
4. We know, that x% equals 87.5 of the output value, so we can write it down as x%=87.5.
5. Now we have two simple equations:
1) 100%=446
2) x%=87.5
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%=446/87.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 87.5 is what percent of 446

100%/x%=446/87.5
(100/x)*x=(446/87.5)*x       - we multiply both sides of the equation by x
100=5.0971428571429*x       - we divide both sides of the equation by (5.0971428571429) to get x
100/5.0971428571429=x
19.618834080717=x
x=19.618834080717

now we have:
87.5 is 19.618834080717% of 446
