89 is what percent of 473 - 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 473 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 473, so we can write it down as 100%=473.
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%=473
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%=473/89
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 473

100%/x%=473/89
(100/x)*x=(473/89)*x       - we multiply both sides of the equation by x
100=5.314606741573*x       - we divide both sides of the equation by (5.314606741573) to get x
100/5.314606741573=x
18.816067653277=x
x=18.816067653277

now we have:
89 is 18.816067653277% of 473
