16.78 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 16.78 of the output value, so we can write it down as x%=16.78.
5. Now we have two simple equations:
1) 100%=212
2) x%=16.78
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%=212/16.78
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 16.78 is what percent of 212

100%/x%=212/16.78
(100/x)*x=(212/16.78)*x       - we multiply both sides of the equation by x
100=12.634088200238*x       - we divide both sides of the equation by (12.634088200238) to get x
100/12.634088200238=x
7.9150943396226=x
x=7.9150943396226

now we have:
16.78 is 7.9150943396226% of 212
