Is it possible to take a cross section of a tetrahedron and get an octagon? why or why not? a.) yes, because an octagon has eight sides, which is twice the number of faces on a tetrahedron. b.) yes, because a tetrahedron is symmetric about its center. c.) no, because the only cross section that can result from a tetrahedron is a triangle. d.) no, because the number of sides on the resulting shape cannot exceed the number of faces on the solid. d.) no, because the number of sides on the resulting shape cannot exceed the number of faces on the solid.

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

hi! i think the answer is 1/2 : )
