31.4 is what percent of 9.7 - 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 9.7 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 9.7, so we can write it down as 100%=9.7.
4. We know, that x% equals 31.4 of the output value, so we can write it down as x%=31.4.
5. Now we have two simple equations:
1) 100%=9.7
2) x%=31.4
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%=9.7/31.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.4 is what percent of 9.7

100%/x%=9.7/31.4
(100/x)*x=(9.7/31.4)*x       - we multiply both sides of the equation by x
100=0.30891719745223*x       - we divide both sides of the equation by (0.30891719745223) to get x
100/0.30891719745223=x
323.71134020619=x
x=323.71134020619

now we have:
31.4 is 323.71134020619% of 9.7
