What is 31 percent of 728.75 - 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 728.75 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 728.75 is 100%, so we can write it down as 728.75=100%.
4. We know, that x is 31% of the output value, so we can write it down as x=31%.
5. Now we have two simple equations:
1) 728.75=100%
2) x=31%
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:
728.75/x=100%/31%
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 31% of 728.75

728.75/x=100/31
(728.75/x)*x=(100/31)*x       - we multiply both sides of the equation by x
728.75=3.2258064516129*x       - we divide both sides of the equation by (3.2258064516129) to get x
728.75/3.2258064516129=x
225.9125=x
x=225.9125

now we have:
31% of 728.75=225.9125
