What is 17 percent of 220 - 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 220 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 220 is 100%, so we can write it down as 220=100%.
4. We know, that x is 17% of the output value, so we can write it down as x=17%.
5. Now we have two simple equations:
1) 220=100%
2) x=17%
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:
220/x=100%/17%
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 17% of 220

220/x=100/17
(220/x)*x=(100/17)*x       - we multiply both sides of the equation by x
220=5.88235294118*x       - we divide both sides of the equation by (5.88235294118) to get x
220/5.88235294118=x
37.4=x
x=37.4

now we have:
17% of 220=37.4
