17.89 is what percent of 79 - 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 79 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 79, so we can write it down as 100%=79.
4. We know, that x% equals 17.89 of the output value, so we can write it down as x%=17.89.
5. Now we have two simple equations:
1) 100%=79
2) x%=17.89
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%=79/17.89
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.89 is what percent of 79

100%/x%=79/17.89
(100/x)*x=(79/17.89)*x       - we multiply both sides of the equation by x
100=4.4158747903857*x       - we divide both sides of the equation by (4.4158747903857) to get x
100/4.4158747903857=x
22.645569620253=x
x=22.645569620253

now we have:
17.89 is 22.645569620253% of 79
