91 is what percent of 5478 - 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 5478 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 5478, so we can write it down as 100%=5478.
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%=5478
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%=5478/91
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 5478

100%/x%=5478/91
(100/x)*x=(5478/91)*x       - we multiply both sides of the equation by x
100=60.197802197802*x       - we divide both sides of the equation by (60.197802197802) to get x
100/60.197802197802=x
1.6611902154071=x
x=1.6611902154071

now we have:
91 is 1.6611902154071% of 5478
