157.6 is what percent of 312.9 - 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 312.9 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 312.9, so we can write it down as 100%=312.9.
4. We know, that x% equals 157.6 of the output value, so we can write it down as x%=157.6.
5. Now we have two simple equations:
1) 100%=312.9
2) x%=157.6
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%=312.9/157.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 157.6 is what percent of 312.9

100%/x%=312.9/157.6
(100/x)*x=(312.9/157.6)*x       - we multiply both sides of the equation by x
100=1.9854060913706*x       - we divide both sides of the equation by (1.9854060913706) to get x
100/1.9854060913706=x
50.36752956216=x
x=50.36752956216

now we have:
157.6 is 50.36752956216% of 312.9
