A stretch of highway that is 12 1/4 miles long has signs every 7/8 of a mile. How many signs are on this stretch of highway?
12 + 1/4 = 49/4
So ..... (49/4) / (7/8) = (49/4) x (8/7) = (49/7) x (8/4) = 7 x 2 = 14 signs
If we assume that there is also a sign at the very beginning, we can add 1 to this = 15 signs
