91 is what percent of 674 - 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 674 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 674, so we can write it down as 100%=674.
4. We know, that x% equals 91 of the output value, so we can write it down as x%=91.
5. Now we have two simple equations:
1) 100%=674
2) x%=91
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%=674/91
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 91 is what percent of 674

100%/x%=674/91
(100/x)*x=(674/91)*x       - we multiply both sides of the equation by x
100=7.4065934065934*x       - we divide both sides of the equation by (7.4065934065934) to get x
100/7.4065934065934=x
13.501483679525=x
x=13.501483679525

now we have:
91 is 13.501483679525% of 674
