79 is what percent of 579 - 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 579 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 579, so we can write it down as 100%=579.
4. We know, that x% equals 79 of the output value, so we can write it down as x%=79.
5. Now we have two simple equations:
1) 100%=579
2) x%=79
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%=579/79
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 79 is what percent of 579

100%/x%=579/79
(100/x)*x=(579/79)*x       - we multiply both sides of the equation by x
100=7.3291139240506*x       - we divide both sides of the equation by (7.3291139240506) to get x
100/7.3291139240506=x
13.644214162349=x
x=13.644214162349

now we have:
79 is 13.644214162349% of 579
