17.59 is what percent of 21.99 - 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 21.99 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 21.99, so we can write it down as 100%=21.99.
4. We know, that x% equals 17.59 of the output value, so we can write it down as x%=17.59.
5. Now we have two simple equations:
1) 100%=21.99
2) x%=17.59
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%=21.99/17.59
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.59 is what percent of 21.99

100%/x%=21.99/17.59
(100/x)*x=(21.99/17.59)*x       - we multiply both sides of the equation by x
100=1.2501421262081*x       - we divide both sides of the equation by (1.2501421262081) to get x
100/1.2501421262081=x
79.990904956799=x
x=79.990904956799

now we have:
17.59 is 79.990904956799% of 21.99
