149.21 is what percent of 500 - 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 500 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 500, so we can write it down as 100%=500.
4. We know, that x% equals 149.21 of the output value, so we can write it down as x%=149.21.
5. Now we have two simple equations:
1) 100%=500
2) x%=149.21
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%=500/149.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 149.21 is what percent of 500

100%/x%=500/149.21
(100/x)*x=(500/149.21)*x       - we multiply both sides of the equation by x
100=3.3509818376784*x       - we divide both sides of the equation by (3.3509818376784) to get x
100/3.3509818376784=x
29.842=x
x=29.842

now we have:
149.21 is 29.842% of 500
