66.66 is what percent of 1400 - 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 1400 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 1400, so we can write it down as 100%=1400.
4. We know, that x% equals 66.66 of the output value, so we can write it down as x%=66.66.
5. Now we have two simple equations:
1) 100%=1400
2) x%=66.66
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%=1400/66.66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66.66 is what percent of 1400

100%/x%=1400/66.66
(100/x)*x=(1400/66.66)*x       - we multiply both sides of the equation by x
100=21.002100210021*x       - we divide both sides of the equation by (21.002100210021) to get x
100/21.002100210021=x
4.7614285714286=x
x=4.7614285714286

now we have:
66.66 is 4.7614285714286% of 1400
