66 is what percent of 149 - 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 149 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 149, so we can write it down as 100%=149.
4. We know, that x% equals 66 of the output value, so we can write it down as x%=66.
5. Now we have two simple equations:
1) 100%=149
2) x%=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%=149/66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66 is what percent of 149

100%/x%=149/66
(100/x)*x=(149/66)*x       - we multiply both sides of the equation by x
100=2.2575757575758*x       - we divide both sides of the equation by (2.2575757575758) to get x
100/2.2575757575758=x
44.295302013423=x
x=44.295302013423

now we have:
66 is 44.295302013423% of 149
