62.9 is what percent of 86 - 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 86 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 86, so we can write it down as 100%=86.
4. We know, that x% equals 62.9 of the output value, so we can write it down as x%=62.9.
5. Now we have two simple equations:
1) 100%=86
2) x%=62.9
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%=86/62.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 62.9 is what percent of 86

100%/x%=86/62.9
(100/x)*x=(86/62.9)*x       - we multiply both sides of the equation by x
100=1.3672496025437*x       - we divide both sides of the equation by (1.3672496025437) to get x
100/1.3672496025437=x
73.139534883721=x
x=73.139534883721

now we have:
62.9 is 73.139534883721% of 86
