2.66666666 is what percent of 4 - 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 4 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 4, so we can write it down as 100%=4.
4. We know, that x% equals 2.66666666 of the output value, so we can write it down as x%=2.66666666.
5. Now we have two simple equations:
1) 100%=4
2) x%=2.66666666
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%=4/2.66666666
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.66666666 is what percent of 4

100%/x%=4/2.66666666
(100/x)*x=(4/2.66666666)*x       - we multiply both sides of the equation by x
100=1.50000000375*x       - we divide both sides of the equation by (1.50000000375) to get x
100/1.50000000375=x
66.6666665=x
x=66.6666665

now we have:
2.66666666 is 66.6666665% of 4
