Question

the middle of 12.7 and 21.2

Answer 1

Answer:

16.95

Step-by-step explanation:

To find the middle we should first,

21.2 - 12.7 = 8.5

and then find the middle of the difference i.e 8.5

8.5/2 = 4.25

now we should add this quotient i.e 4.25 to 12.7

12.7 + 4.25 = 16.95

There you go. That's your answer.

Coming to the reason why i chose this method is because it is the easiest. By finding the elapsed total number ( 8.5), we can find its middle and so the middle of any two given values.
