145.57 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 145.57 of the output value, so we can write it down as x%=145.57.
5. Now we have two simple equations:
1) 100%=149
2) x%=145.57
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%=149/145.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 145.57 is what percent of 149

100%/x%=149/145.57
(100/x)*x=(149/145.57)*x       - we multiply both sides of the equation by x
100=1.0235625472281*x       - we divide both sides of the equation by (1.0235625472281) to get x
100/1.0235625472281=x
97.697986577181=x
x=97.697986577181

now we have:
145.57 is 97.697986577181% of 149
