85 is what percent of 698 - 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 698 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 698, so we can write it down as 100%=698.
4. We know, that x% equals 85 of the output value, so we can write it down as x%=85.
5. Now we have two simple equations:
1) 100%=698
2) x%=85
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%=698/85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 85 is what percent of 698

100%/x%=698/85
(100/x)*x=(698/85)*x       - we multiply both sides of the equation by x
100=8.2117647058824*x       - we divide both sides of the equation by (8.2117647058824) to get x
100/8.2117647058824=x
12.177650429799=x
x=12.177650429799

now we have:
85 is 12.177650429799% of 698
