What is 20 percent of 227.98 - 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 227.98 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 227.98 is 100%, so we can write it down as 227.98=100%.
4. We know, that x is 20% of the output value, so we can write it down as x=20%.
5. Now we have two simple equations:
1) 227.98=100%
2) x=20%
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:
227.98/x=100%/20%
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 20% of 227.98

227.98/x=100/20
(227.98/x)*x=(100/20)*x       - we multiply both sides of the equation by x
227.98=5*x       - we divide both sides of the equation by (5) to get x
227.98/5=x
45.596=x
x=45.596

now we have:
20% of 227.98=45.596
