62 is what percent of 15.5 - 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 15.5 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 15.5, so we can write it down as 100%=15.5.
4. We know, that x% equals 62 of the output value, so we can write it down as x%=62.
5. Now we have two simple equations:
1) 100%=15.5
2) x%=62
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%=15.5/62
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 62 is what percent of 15.5

100%/x%=15.5/62
(100/x)*x=(15.5/62)*x       - we multiply both sides of the equation by x
100=0.25*x       - we divide both sides of the equation by (0.25) to get x
100/0.25=x
400=x
x=400

now we have:
62 is 400% of 15.5
