4.37 is what percent of 9.99 - 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 9.99 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 9.99, so we can write it down as 100%=9.99.
4. We know, that x% equals 4.37 of the output value, so we can write it down as x%=4.37.
5. Now we have two simple equations:
1) 100%=9.99
2) x%=4.37
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%=9.99/4.37
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.37 is what percent of 9.99

100%/x%=9.99/4.37
(100/x)*x=(9.99/4.37)*x       - we multiply both sides of the equation by x
100=2.2860411899314*x       - we divide both sides of the equation by (2.2860411899314) to get x
100/2.2860411899314=x
43.743743743744=x
x=43.743743743744

now we have:
4.37 is 43.743743743744% of 9.99
