54 is what percent of 1220 - 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 1220 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 1220, so we can write it down as 100%=1220.
4. We know, that x% equals 54 of the output value, so we can write it down as x%=54.
5. Now we have two simple equations:
1) 100%=1220
2) x%=54
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%=1220/54
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 54 is what percent of 1220

100%/x%=1220/54
(100/x)*x=(1220/54)*x       - we multiply both sides of the equation by x
100=22.592592592593*x       - we divide both sides of the equation by (22.592592592593) to get x
100/22.592592592593=x
4.4262295081967=x
x=4.4262295081967

now we have:
54 is 4.4262295081967% of 1220
