8 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 8 of the output value, so we can write it down as x%=8.
5. Now we have two simple equations:
1) 100%=212
2) x%=8
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%=212/8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8 is what percent of 212

100%/x%=212/8
(100/x)*x=(212/8)*x       - we multiply both sides of the equation by x
100=26.5*x       - we divide both sides of the equation by (26.5) to get x
100/26.5=x
3.7735849056604=x
x=3.7735849056604

now we have:
8 is 3.7735849056604% of 212
