What is 63 percent of 27 - 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 27 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 27 is 100%, so we can write it down as 27=100%.
4. We know, that x is 63% of the output value, so we can write it down as x=63%.
5. Now we have two simple equations:
1) 27=100%
2) x=63%
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:
27/x=100%/63%
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 63% of 27

27/x=100/63
(27/x)*x=(100/63)*x       - we multiply both sides of the equation by x
27=1.5873015873016*x       - we divide both sides of the equation by (1.5873015873016) to get x
27/1.5873015873016=x
17.01=x
x=17.01

now we have:
63% of 27=17.01
