17.04 is what percent of 21.38 - 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 21.38 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 21.38, so we can write it down as 100%=21.38.
4. We know, that x% equals 17.04 of the output value, so we can write it down as x%=17.04.
5. Now we have two simple equations:
1) 100%=21.38
2) x%=17.04
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%=21.38/17.04
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.04 is what percent of 21.38

100%/x%=21.38/17.04
(100/x)*x=(21.38/17.04)*x       - we multiply both sides of the equation by x
100=1.2546948356808*x       - we divide both sides of the equation by (1.2546948356808) to get x
100/1.2546948356808=x
79.700654817587=x
x=79.700654817587

now we have:
17.04 is 79.700654817587% of 21.38
