Carter has 60 balloons. 4 12 of the balloons are black, and 3 12 of the balloons are white. The rest of the balloons are red. Which series of calculations shows how many red balloons Carter has? A. 12 12 = 3 × 4 12 ; 1 12 × 60 = 5 ; 4 × 5 = 20 red ballons B. 4 12 + 3 12 = 7 12 ; 1 12 × 60 = 5 ; 7 × 5 = 35 red balloons C. 12 12 − 4 12 − 3 12 = 5 12 ; 1 12 × 60 = 6 ; 6 × 5 = 30 red balloons D. 4 12 + 3 12 = 7 12 ; 12 12 − 7 12 = 5 12 ; 1 12 × 60 = 5 ; 5 × 5 = 25 red balloons
