70.3 is what percent of 310.8 - 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 310.8 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 310.8, so we can write it down as 100%=310.8.
4. We know, that x% equals 70.3 of the output value, so we can write it down as x%=70.3.
5. Now we have two simple equations:
1) 100%=310.8
2) x%=70.3
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%=310.8/70.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 70.3 is what percent of 310.8

100%/x%=310.8/70.3
(100/x)*x=(310.8/70.3)*x       - we multiply both sides of the equation by x
100=4.4210526315789*x       - we divide both sides of the equation by (4.4210526315789) to get x
100/4.4210526315789=x
22.619047619048=x
x=22.619047619048

now we have:
70.3 is 22.619047619048% of 310.8
