What is 21.6 percent of 74 - 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 74 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 74 is 100%, so we can write it down as 74=100%.
4. We know, that x is 21.6% of the output value, so we can write it down as x=21.6%.
5. Now we have two simple equations:
1) 74=100%
2) x=21.6%
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:
74/x=100%/21.6%
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 21.6% of 74

74/x=100/21.6
(74/x)*x=(100/21.6)*x       - we multiply both sides of the equation by x
74=4.6296296296296*x       - we divide both sides of the equation by (4.6296296296296) to get x
74/4.6296296296296=x
15.984=x
x=15.984

now we have:
21.6% of 74=15.984
