1.99 is what percent of 4.99 - 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 4.99 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 4.99, so we can write it down as 100%=4.99.
4. We know, that x% equals 1.99 of the output value, so we can write it down as x%=1.99.
5. Now we have two simple equations:
1) 100%=4.99
2) x%=1.99
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%=4.99/1.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.99 is what percent of 4.99

100%/x%=4.99/1.99
(100/x)*x=(4.99/1.99)*x       - we multiply both sides of the equation by x
100=2.5075376884422*x       - we divide both sides of the equation by (2.5075376884422) to get x
100/2.5075376884422=x
39.879759519038=x
x=39.879759519038

now we have:
1.99 is 39.879759519038% of 4.99
