37.99 is what percent of 45.99 - 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 45.99 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 45.99, so we can write it down as 100%=45.99.
4. We know, that x% equals 37.99 of the output value, so we can write it down as x%=37.99.
5. Now we have two simple equations:
1) 100%=45.99
2) x%=37.99
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%=45.99/37.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 37.99 is what percent of 45.99

100%/x%=45.99/37.99
(100/x)*x=(45.99/37.99)*x       - we multiply both sides of the equation by x
100=1.2105817320347*x       - we divide both sides of the equation by (1.2105817320347) to get x
100/1.2105817320347=x
82.604914111763=x
x=82.604914111763

now we have:
37.99 is 82.604914111763% of 45.99
