15.45 is what percent of 22 - 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 22 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 22, so we can write it down as 100%=22.
4. We know, that x% equals 15.45 of the output value, so we can write it down as x%=15.45.
5. Now we have two simple equations:
1) 100%=22
2) x%=15.45
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%=22/15.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.45 is what percent of 22

100%/x%=22/15.45
(100/x)*x=(22/15.45)*x       - we multiply both sides of the equation by x
100=1.4239482200647*x       - we divide both sides of the equation by (1.4239482200647) to get x
100/1.4239482200647=x
70.227272727273=x
x=70.227272727273

now we have:
15.45 is 70.227272727273% of 22
