143.9 is what percent of 153.5 - 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 153.5 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 153.5, so we can write it down as 100%=153.5.
4. We know, that x% equals 143.9 of the output value, so we can write it down as x%=143.9.
5. Now we have two simple equations:
1) 100%=153.5
2) x%=143.9
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%=153.5/143.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 143.9 is what percent of 153.5

100%/x%=153.5/143.9
(100/x)*x=(153.5/143.9)*x       - we multiply both sides of the equation by x
100=1.0667129951355*x       - we divide both sides of the equation by (1.0667129951355) to get x
100/1.0667129951355=x
93.745928338762=x
x=93.745928338762

now we have:
143.9 is 93.745928338762% of 153.5
