A bag contains 10 white golf balls and 6 striped golf balls. A golfer wants to add 112 golf balls to the bag. He wants the ratio of white to striped golf balls to remain the same. How many of each should he add?

Ms. Sue,
Let w = white balls. Cross multiply and solve for w.
10/16 = w/112
16w = 1120
w = 70
Let s = striped
112  70 = s
? = s

17: cross multiply
10/16 = w/112
16w = 1120
W=70
Striped golf balls = s
11270= 42
18.
V (12,4)
W (4,8)
X (6,4)
Y (6,10)
19. They are not similar because none of the coordinates would divide or multiply to get the larger number. Example: take 2.4ft and multiply 3 you will get 7.2. Again, take 2.4ft and multiply 4 and you will get 9.4
20. Yes, they are equivalent. 4 x 21= 84
6 x 14= 84
