0.38 is what percent of 21.29 - 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 21.29 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 21.29, so we can write it down as 100%=21.29.
4. We know, that x% equals 0.38 of the output value, so we can write it down as x%=0.38.
5. Now we have two simple equations:
1) 100%=21.29
2) x%=0.38
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%=21.29/0.38
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.38 is what percent of 21.29

100%/x%=21.29/0.38
(100/x)*x=(21.29/0.38)*x       - we multiply both sides of the equation by x
100=56.026315789474*x       - we divide both sides of the equation by (56.026315789474) to get x
100/56.026315789474=x
1.7848755284171=x
x=1.7848755284171

now we have:
0.38 is 1.7848755284171% of 21.29
