87 is what percent of 382 - 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 382 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 382, so we can write it down as 100%=382.
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%=382
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%=382/87
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 382

100%/x%=382/87
(100/x)*x=(382/87)*x       - we multiply both sides of the equation by x
100=4.3908045977011*x       - we divide both sides of the equation by (4.3908045977011) to get x
100/4.3908045977011=x
22.774869109948=x
x=22.774869109948

now we have:
87 is 22.774869109948% of 382
