26.67 is what percent of 42 - 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 42 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 42, so we can write it down as 100%=42.
4. We know, that x% equals 26.67 of the output value, so we can write it down as x%=26.67.
5. Now we have two simple equations:
1) 100%=42
2) x%=26.67
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%=42/26.67
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 26.67 is what percent of 42

100%/x%=42/26.67
(100/x)*x=(42/26.67)*x       - we multiply both sides of the equation by x
100=1.5748031496063*x       - we divide both sides of the equation by (1.5748031496063) to get x
100/1.5748031496063=x
63.5=x
x=63.5

now we have:
26.67 is 63.5% of 42
