42.8 is what percent of 6321.95 - 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 6321.95 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 6321.95, so we can write it down as 100%=6321.95.
4. We know, that x% equals 42.8 of the output value, so we can write it down as x%=42.8.
5. Now we have two simple equations:
1) 100%=6321.95
2) x%=42.8
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%=6321.95/42.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 42.8 is what percent of 6321.95

100%/x%=6321.95/42.8
(100/x)*x=(6321.95/42.8)*x       - we multiply both sides of the equation by x
100=147.70911214953*x       - we divide both sides of the equation by (147.70911214953) to get x
100/147.70911214953=x
0.67700630343486=x
x=0.67700630343486

now we have:
42.8 is 0.67700630343486% of 6321.95
