2.12 is what percent of 19.88 - 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 19.88 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 19.88, so we can write it down as 100%=19.88.
4. We know, that x% equals 2.12 of the output value, so we can write it down as x%=2.12.
5. Now we have two simple equations:
1) 100%=19.88
2) x%=2.12
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%=19.88/2.12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.12 is what percent of 19.88

100%/x%=19.88/2.12
(100/x)*x=(19.88/2.12)*x       - we multiply both sides of the equation by x
100=9.377358490566*x       - we divide both sides of the equation by (9.377358490566) to get x
100/9.377358490566=x
10.663983903421=x
x=10.663983903421

now we have:
2.12 is 10.663983903421% of 19.88
