Answer 2

Answer:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 642 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 642, so we can write it down as 100%=642.

4. We know, that x% equals 16 of the output value, so we can write it down as x%=16.

5. Now we have two simple equations:

1) 100%=642

2) x%=16

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%=642/16

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 16 is what percent of 642

100%/x%=642/16

(100/x)*x=(642/16)*x - we multiply both sides of the equation by x

100=40.125*x - we divide both sides of the equation by (40.125) to get x

100/40.125=x

2.4922118380062=x

x=2.4922118380062

now we have:

16 is 2.4922118380062% of 642
