21.12 is what percent of 373 - 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 373 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 373, so we can write it down as 100%=373.
4. We know, that x% equals 21.12 of the output value, so we can write it down as x%=21.12.
5. Now we have two simple equations:
1) 100%=373
2) x%=21.12
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%=373/21.12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.12 is what percent of 373

100%/x%=373/21.12
(100/x)*x=(373/21.12)*x       - we multiply both sides of the equation by x
100=17.660984848485*x       - we divide both sides of the equation by (17.660984848485) to get x
100/17.660984848485=x
5.6621983914209=x
x=5.6621983914209

now we have:
21.12 is 5.6621983914209% of 373
