91 is what percent of 1624 - 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 1624 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 1624, so we can write it down as 100%=1624.
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%=1624
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%=1624/91
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 1624

100%/x%=1624/91
(100/x)*x=(1624/91)*x       - we multiply both sides of the equation by x
100=17.846153846154*x       - we divide both sides of the equation by (17.846153846154) to get x
100/17.846153846154=x
5.6034482758621=x
x=5.6034482758621

now we have:
91 is 5.6034482758621% of 1624
