10.7 is what percent of 12.4 - 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 12.4 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 12.4, so we can write it down as 100%=12.4.
4. We know, that x% equals 10.7 of the output value, so we can write it down as x%=10.7.
5. Now we have two simple equations:
1) 100%=12.4
2) x%=10.7
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%=12.4/10.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10.7 is what percent of 12.4

100%/x%=12.4/10.7
(100/x)*x=(12.4/10.7)*x       - we multiply both sides of the equation by x
100=1.1588785046729*x       - we divide both sides of the equation by (1.1588785046729) to get x
100/1.1588785046729=x
86.290322580645=x
x=86.290322580645

now we have:
10.7 is 86.290322580645% of 12.4
