90 is what percent of 5339 - 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 5339 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 5339, so we can write it down as 100%=5339.
4. We know, that x% equals 90 of the output value, so we can write it down as x%=90.
5. Now we have two simple equations:
1) 100%=5339
2) x%=90
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%=5339/90
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 90 is what percent of 5339

100%/x%=5339/90
(100/x)*x=(5339/90)*x       - we multiply both sides of the equation by x
100=59.322222222222*x       - we divide both sides of the equation by (59.322222222222) to get x
100/59.322222222222=x
1.6857089342574=x
x=1.6857089342574

now we have:
90 is 1.6857089342574% of 5339
