Answer:
A counting number is a whole number, then we have that:
"a counting number is added to 3"
This is N + 3, where N is a whole number
"...and the sum is divided by 2..."
Now we have:
(N + 3)/2
"the quotient will be an even number."
(N + 3)/2 = even number.
None of the options is in this form, but we could take the first one:
(8 + 4)/2
And write the numerator as:
8 + 4 = 8 + ( 3 + 1) = 8 + 3 + 1 = (8 + 1) + 3 = 9 + 3.
Then we have:
(9 + 3)/2 = 6 .
In this case, we have a counting number, 9 , added to 3, and the sum is divided by 2, and the quotient is an even number, 6.
