There isn’t enough information to this problem for it to be solved.
However, I assumed that it was supposed to read the following:
“The sum of the multiplicative inverse of two positive CONSECUTIVE even integers is 5/12.find the integers.”
From this assumption, let the first even integer be x
Then the following consecutive even integer will be x + 2
Since the assumption is that the sum of the multiplicative inverse of these 2 numbers is 5/12, then
Then, 12x + 24 + 12x = 5x(x + 2)
5x(x – 4) + 6(x – 4) = 0
(5x + 6)(x – 4) = 0
Since 5x + 6 = 0 will produce a decimal, we eliminate this x-value as it was given that the 2 numbers are INTEGERS, or whole numbers. Therefore, the first even integer is 4, which makes the second even integer, 6.
