Answer:

Step-by-step explanation:

Find LCM of 4,5,8 = 40

Then find equivalent fractions

2/4 = 2*10/4*10 = 20/40

3/5 = 3*8/5*8 = 24/40

6/8 = 6*5/8*5 = 30/40

20/40+24/40+30/40 = (20+24+30)/40

= 74/40 = 37/20

and u pick any 2 of those numbers and multiply them u will end up with an odd numbered multiple of 3

and if u pick out any 2 numbers in ur set..and do any of the other things in ur answer choices, it will not always be an odd numbered multiple of 3
