What is 89.75 percent of 720 - 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 720 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 720 is 100%, so we can write it down as 720=100%.
4. We know, that x is 89.75% of the output value, so we can write it down as x=89.75%.
5. Now we have two simple equations:
1) 720=100%
2) x=89.75%
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:
720/x=100%/89.75%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 89.75% of 720

720/x=100/89.75
(720/x)*x=(100/89.75)*x       - we multiply both sides of the equation by x
720=1.1142061281337*x       - we divide both sides of the equation by (1.1142061281337) to get x
720/1.1142061281337=x
646.2=x
x=646.2

now we have:
89.75% of 720=646.2
