7 is what percent of 44.45 - 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 44.45 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 44.45, so we can write it down as 100%=44.45.
4. We know, that x% equals 7 of the output value, so we can write it down as x%=7.
5. Now we have two simple equations:
1) 100%=44.45
2) x%=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%=44.45/7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7 is what percent of 44.45

100%/x%=44.45/7
(100/x)*x=(44.45/7)*x       - we multiply both sides of the equation by x
100=6.35*x       - we divide both sides of the equation by (6.35) to get x
100/6.35=x
15.748031496063=x
x=15.748031496063

now we have:
7 is 15.748031496063% of 44.45
