87 is what percent of 433 - 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 433 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 433, so we can write it down as 100%=433.
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%=433
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%=433/87
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 433

100%/x%=433/87
(100/x)*x=(433/87)*x       - we multiply both sides of the equation by x
100=4.9770114942529*x       - we divide both sides of the equation by (4.9770114942529) to get x
100/4.9770114942529=x
20.092378752887=x
x=20.092378752887

now we have:
87 is 20.092378752887% of 433
