79 is what percent of 1579 - 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 1579 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 1579, so we can write it down as 100%=1579.
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%=1579
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%=1579/79
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 1579

100%/x%=1579/79
(100/x)*x=(1579/79)*x       - we multiply both sides of the equation by x
100=19.987341772152*x       - we divide both sides of the equation by (19.987341772152) to get x
100/19.987341772152=x
5.0031665611146=x
x=5.0031665611146

now we have:
79 is 5.0031665611146% of 1579
