They will get a Green Ribbon and a Blue ribbon because 1/4 and 1/8 have a common denominator with 3/4 This means ever 1/4 a mile you get a blue ribbon and in that there is 1/4, 2/4, 3/4 and 4/4every 1/8 mile you get a green ribbon and in 1/8 there is 1/8, 2/8, 3/8, 4/8, 5/8, 6/8 (which is equal to 3/4 because 6 divided by 2 is 3 and 8 divided by 2 is 4), 7/8, and 8/8For 1/2 there is only 1/2 and 2/2 Hope this helped=)
