215.5 is what percent of 379 - 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 379 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 379, so we can write it down as 100%=379.
4. We know, that x% equals 215.5 of the output value, so we can write it down as x%=215.5.
5. Now we have two simple equations:
1) 100%=379
2) x%=215.5
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%=379/215.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 215.5 is what percent of 379

100%/x%=379/215.5
(100/x)*x=(379/215.5)*x       - we multiply both sides of the equation by x
100=1.7587006960557*x       - we divide both sides of the equation by (1.7587006960557) to get x
100/1.7587006960557=x
56.860158311346=x
x=56.860158311346

now we have:
215.5 is 56.860158311346% of 379
