15 is what percent of 10.56 - 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 10.56 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 10.56, so we can write it down as 100%=10.56.
4. We know, that x% equals 15 of the output value, so we can write it down as x%=15.
5. Now we have two simple equations:
1) 100%=10.56
2) x%=15
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%=10.56/15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15 is what percent of 10.56

100%/x%=10.56/15
(100/x)*x=(10.56/15)*x       - we multiply both sides of the equation by x
100=0.704*x       - we divide both sides of the equation by (0.704) to get x
100/0.704=x
142.04545454545=x
x=142.04545454545

now we have:
15 is 142.04545454545% of 10.56
