What is 72 percent of 63 - 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 63 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 63 is 100%, so we can write it down as 63=100%.
4. We know, that x is 72% of the output value, so we can write it down as x=72%.
5. Now we have two simple equations:
1) 63=100%
2) x=72%
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:
63/x=100%/72%
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 72% of 63

63/x=100/72
(63/x)*x=(100/72)*x       - we multiply both sides of the equation by x
63=1.38888888889*x       - we divide both sides of the equation by (1.38888888889) to get x
63/1.38888888889=x
45.36=x
x=45.36

now we have:
72% of 63=45.36
