5 Proportions are similar to analogies.
Green x Sacramento Wash. D.C. = = Grass Sky California x x = Blue x = U.S.A. Hand Shoe = Glove x x = Foot x = Shoebox or Closet

6 If it takes 6 cups of flour to make 54 cookies,
how many cookies can be made with 10 cups? Let x = the number of cookies cups 6 10 = cookies 54 x 6x = 540 x = 90 cookies

7 A factory can produce 91 widgets in 7 hours.
How many widgets can it produce in 12 hours? Let x = the number of widgets widgets 91 x = hours 7 12 91(12) = 7x 1092 = 7x 156 = x x = 156 widgets
