54 is what percent of 154 - 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 154 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 154, so we can write it down as 100%=154.
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%=154
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%=154/54
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 154

100%/x%=154/54
(100/x)*x=(154/54)*x       - we multiply both sides of the equation by x
100=2.85185185185*x       - we divide both sides of the equation by (2.85185185185) to get x
100/2.85185185185=x
35.0649350649=x
x=35.0649350649

now we have:
54 is 35.0649350649% of 154
