31.6 is what percent of 51.4 - 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 51.4 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 51.4, so we can write it down as 100%=51.4.
4. We know, that x% equals 31.6 of the output value, so we can write it down as x%=31.6.
5. Now we have two simple equations:
1) 100%=51.4
2) x%=31.6
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%=51.4/31.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.6 is what percent of 51.4

100%/x%=51.4/31.6
(100/x)*x=(51.4/31.6)*x       - we multiply both sides of the equation by x
100=1.626582278481*x       - we divide both sides of the equation by (1.626582278481) to get x
100/1.626582278481=x
61.47859922179=x
x=61.47859922179

now we have:
31.6 is 61.47859922179% of 51.4
