What is 20 percent of 359.97 - 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 359.97 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 359.97 is 100%, so we can write it down as 359.97=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) 359.97=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:
359.97/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 359.97

359.97/x=100/20
(359.97/x)*x=(100/20)*x       - we multiply both sides of the equation by x
359.97=5*x       - we divide both sides of the equation by (5) to get x
359.97/5=x
71.994=x
x=71.994

now we have:
20% of 359.97=71.994
