4.21 is what percent of 33.75 - 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 33.75 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 33.75, so we can write it down as 100%=33.75.
4. We know, that x% equals 4.21 of the output value, so we can write it down as x%=4.21.
5. Now we have two simple equations:
1) 100%=33.75
2) x%=4.21
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%=33.75/4.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.21 is what percent of 33.75

100%/x%=33.75/4.21
(100/x)*x=(33.75/4.21)*x       - we multiply both sides of the equation by x
100=8.0166270783848*x       - we divide both sides of the equation by (8.0166270783848) to get x
100/8.0166270783848=x
12.474074074074=x
x=12.474074074074

now we have:
4.21 is 12.474074074074% of 33.75
