69.47 is what percent of 89 - 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 89 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 89, so we can write it down as 100%=89.
4. We know, that x% equals 69.47 of the output value, so we can write it down as x%=69.47.
5. Now we have two simple equations:
1) 100%=89
2) x%=69.47
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%=89/69.47
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 69.47 is what percent of 89

100%/x%=89/69.47
(100/x)*x=(89/69.47)*x       - we multiply both sides of the equation by x
100=1.2811285446956*x       - we divide both sides of the equation by (1.2811285446956) to get x
100/1.2811285446956=x
78.056179775281=x
x=78.056179775281

now we have:
69.47 is 78.056179775281% of 89
