Well 1 yard is 36 inches so 25 yards is 900 and then divide the 900 by 22 which equals 40.9090 but you have to put this down to 40 and because you have 3 ribbons it's 40 x 3 = 120!
86% if im correct, i got this answer because of the standard deviation, even though, im not 100% sure im correct, do some researching for this answer on top of mine!
