Cheryl is organizing her movie collection. If each movie case is 3/ 4 inch wide, how may movies can fit on a shelf 5 1 /4 feet wide?

Question

1. Show your work please

Answer 1

5 1/4 divided by 3/4 = 21/4 divided by 3/4 = 21/3 = 7 movies can fit on the shelf

5 1/4 = 21/4

(21/4)/(3/4) = (21/4)(4/3) = 21/3

dividing by a fraction is the same as multiplying by the inverse of the fraction, the 4's cancel leaving only 21/3 = 7
