F

Step-by-step explanation:

Let the number of birds flying in group be "x"

When said, we need HALF of us, it means, HALF of x, or

And then, plus the new bird (1 only) to make 100, so we can say:

Now, we can solve the equation algebraically to get "x", to get the number of birds flying:

Answer is 66

Answer choice F is right

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
