1/2 = 0.50

(0.85 - 0.50) / 2 = 0.35/2 = 0.175

0.50 + 0.175 = 0.675 or 27/40 <==
0.85 - 0.175 = 0.675 or 27/40 <==

** first, u take the difference of the numbers and divide it by 2....then u add that to 0.50 and subtract that from 0.85 and that is ur middle number

1/2=0.5
0.85-0.5=0.35 Find out the difference between the two numbers
0.35÷2=0.175 Divide the difference by two
0.85-0.175=0.675
0.5+0.175=0.675
CHECK to see if that number works both ways
The answer is 0.675
