3.45 is what percent of 16 - 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 16 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 100% equals 16, so we can write it down as 100%=16.
4. We know, that x% equals 3.45 of the output value, so we can write it down as x%=3.45.
5. Now we have two simple equations:
1) 100%=16
2) x%=3.45
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:
100%/x%=16/3.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.45 is what percent of 16

100%/x%=16/3.45
(100/x)*x=(16/3.45)*x       - we multiply both sides of the equation by x
100=4.6376811594203*x       - we divide both sides of the equation by (4.6376811594203) to get x
100/4.6376811594203=x
21.5625=x
x=21.5625

now we have:
3.45 is 21.5625% of 16
