What’s Happening? Lesson- C&S 3.2! Begin HW?

Question How can you use unit rates, proportions, equations, and rate tables to scale a variety of units?

You can also use proportions to convert measurements. For example, 1 cup = x cups 8 fluid ounces 50 fluid ounces What would solving this proportion tell you? It will tell you how many cups 50 fluid ounces make. 50 fluid ounces = 6.25 cups

5 mi 2 hrs. 1.25 hrs. Find a unit rate? 5 mi. x mi. 2 hrs. = 5 mi. 2 hrs. x mi. 1 hr. 15 min. = 1.25 hrs. = 5 mi 2 hrs. x mi. 1 hr. = 2.5 mi. 1 hr. = x mi. 1.25 hr. = 3.125 mi.

4 mi. .75 mi. .25 hrs. .75 mi. .25 hrs. 3 mi. 1 hr. Find a unit rate? = .75 mi. .25 hrs. x mi. hr. = = .75 mi. .25 hrs. 3 mi. 1 hr. = 4 mi. 4 mi. hr. =

128 gr. fat 16 cups x gr. fat 1 Gallon = = x gr. fat = 8 gr. fat 1 cup Different Unit rate! Unit rate!

3 lawns 2/3 tank x lawns 1 tank = 4.5 one-acre lawns =

276 cal. 6 oz. 16 oz. 46 cal./oz. 1 oz. x cal. x cal. 1 pound 1 oz. = x cal. 1 oz. = 46 cal./oz. = 46 cal. 1 oz. = 736 cal. 16 oz. = 736 cal. 1 lb. = 736 cal./lb.

28.8 beads/ft. 2.4 beads/in. 12 beads 5 in. = x beads 1 ft. = 12 beads

52 and 1/12 cm. 20.083 in 12 beads 5 in. = 50 beads x cm. = 12 beads x in. = 20.083 in 50 beads 20.083 in. = 50 beads x cm. = 52 and 1/12 cm.
