79 is what percent of 1139 - 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 1139 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 1139, so we can write it down as 100%=1139.
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%=1139
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%=1139/79
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 1139

100%/x%=1139/79
(100/x)*x=(1139/79)*x       - we multiply both sides of the equation by x
100=14.417721518987*x       - we divide both sides of the equation by (14.417721518987) to get x
100/14.417721518987=x
6.9359086918349=x
x=6.9359086918349

now we have:
79 is 6.9359086918349% of 1139
