19.61 is what percent of 212 - 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 212 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 212, so we can write it down as 100%=212.
4. We know, that x% equals 19.61 of the output value, so we can write it down as x%=19.61.
5. Now we have two simple equations:
1) 100%=212
2) x%=19.61
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%=212/19.61
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.61 is what percent of 212

100%/x%=212/19.61
(100/x)*x=(212/19.61)*x       - we multiply both sides of the equation by x
100=10.810810810811*x       - we divide both sides of the equation by (10.810810810811) to get x
100/10.810810810811=x
9.25=x
x=9.25

now we have:
19.61 is 9.25% of 212
