21.53 is what percent of 49.99 - 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 49.99 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 49.99, so we can write it down as 100%=49.99.
4. We know, that x% equals 21.53 of the output value, so we can write it down as x%=21.53.
5. Now we have two simple equations:
1) 100%=49.99
2) x%=21.53
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%=49.99/21.53
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.53 is what percent of 49.99

100%/x%=49.99/21.53
(100/x)*x=(49.99/21.53)*x       - we multiply both sides of the equation by x
100=2.3218764514631*x       - we divide both sides of the equation by (2.3218764514631) to get x
100/2.3218764514631=x
43.068613722745=x
x=43.068613722745

now we have:
21.53 is 43.068613722745% of 49.99
