37.7 is what percent of 54 - 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 54 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 54, so we can write it down as 100%=54.
4. We know, that x% equals 37.7 of the output value, so we can write it down as x%=37.7.
5. Now we have two simple equations:
1) 100%=54
2) x%=37.7
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%=54/37.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 37.7 is what percent of 54

100%/x%=54/37.7
(100/x)*x=(54/37.7)*x       - we multiply both sides of the equation by x
100=1.4323607427056*x       - we divide both sides of the equation by (1.4323607427056) to get x
100/1.4323607427056=x
69.814814814815=x
x=69.814814814815

now we have:
37.7 is 69.814814814815% of 54
