89 is what percent of 143 - 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 143 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 143, so we can write it down as 100%=143.
4. We know, that x% equals 89 of the output value, so we can write it down as x%=89.
5. Now we have two simple equations:
1) 100%=143
2) x%=89
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%=143/89
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 89 is what percent of 143

100%/x%=143/89
(100/x)*x=(143/89)*x       - we multiply both sides of the equation by x
100=1.60674157303*x       - we divide both sides of the equation by (1.60674157303) to get x
100/1.60674157303=x
62.2377622378=x
x=62.2377622378

now we have:
89 is 62.2377622378% of 143
