753.5 is what percent of 21000 - 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 21000 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 21000, so we can write it down as 100%=21000.
4. We know, that x% equals 753.5 of the output value, so we can write it down as x%=753.5.
5. Now we have two simple equations:
1) 100%=21000
2) x%=753.5
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%=21000/753.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 753.5 is what percent of 21000

100%/x%=21000/753.5
(100/x)*x=(21000/753.5)*x       - we multiply both sides of the equation by x
100=27.869940278699*x       - we divide both sides of the equation by (27.869940278699) to get x
100/27.869940278699=x
3.5880952380952=x
x=3.5880952380952

now we have:
753.5 is 3.5880952380952% of 21000
