0.66 is what percent of 6.99 - 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 6.99 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 6.99, so we can write it down as 100%=6.99.
4. We know, that x% equals 0.66 of the output value, so we can write it down as x%=0.66.
5. Now we have two simple equations:
1) 100%=6.99
2) x%=0.66
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%=6.99/0.66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.66 is what percent of 6.99

100%/x%=6.99/0.66
(100/x)*x=(6.99/0.66)*x       - we multiply both sides of the equation by x
100=10.590909090909*x       - we divide both sides of the equation by (10.590909090909) to get x
100/10.590909090909=x
9.4420600858369=x
x=9.4420600858369

now we have:
0.66 is 9.4420600858369% of 6.99
