10 is what percent of 50.2 - 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 50.2 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 50.2, so we can write it down as 100%=50.2.
4. We know, that x% equals 10 of the output value, so we can write it down as x%=10.
5. Now we have two simple equations:
1) 100%=50.2
2) x%=10
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%=50.2/10
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10 is what percent of 50.2

100%/x%=50.2/10
(100/x)*x=(50.2/10)*x       - we multiply both sides of the equation by x
100=5.02*x       - we divide both sides of the equation by (5.02) to get x
100/5.02=x
19.9203187251=x
x=19.9203187251

now we have:
10 is 19.9203187251% of 50.2
