0.67 is what percent of 8.5 - 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 8.5 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 8.5, so we can write it down as 100%=8.5.
4. We know, that x% equals 0.67 of the output value, so we can write it down as x%=0.67.
5. Now we have two simple equations:
1) 100%=8.5
2) x%=0.67
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%=8.5/0.67
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.67 is what percent of 8.5

100%/x%=8.5/0.67
(100/x)*x=(8.5/0.67)*x       - we multiply both sides of the equation by x
100=12.686567164179*x       - we divide both sides of the equation by (12.686567164179) to get x
100/12.686567164179=x
7.8823529411765=x
x=7.8823529411765

now we have:
0.67 is 7.8823529411765% of 8.5
