10. Tuesday, Oct 7 Lesson 6.4.5 Convert Measurement Units

11. Objective: To understand how to change units of measurement in the customary system.

12. Convert Measurement Units A relationship within the same type of unit of measurement can be written as a ratio. Example 1 yard = 3 feet can be written as 1 yard 3 feet

13. Convert Measurement Units These ratios can be used to set up a proportion to solve measurement problems. Example 1 yard 6 yards 3 feet = ? feet

14. Convert Measurement Units If you do not know these relationships, use the 6 th grade reference sheet.

15. Convert Measurement Units Convert 20 feet to inches. Step 1 – Identify the direct relationship between the units in the problem and write as a ratio. How many ____ to how many ____?

16. Convert Measurement Units Convert 20 feet to inches. Step 1 – Identify the direct relationship between the units in the problem and write as a ratio. 1 foot 12 inches 12 inches or 1 foot

17. Convert Measurement Units Convert 20 feet to inches. Step 2 – Create a second ratio from the numbers in the original problem.

18. Convert Measurement Units Convert 20 feet to inches. Step 2 – Create a second ratio from the numbers in the original problem. 20 feet ? inches ? inches or 20 feet

19. Convert Measurement Units Convert 20 feet to inches. Step 3 – Create a proportion with the two ratios, making sure the same units are in the numerator on each ratio.

20. Convert Measurement Units Convert 20 feet to inches. Step 3 – Create a proportion with the two ratios, making sure the same units are in the numerator on each ratio. 20 feet 1 foot ? inches = 12 inches

21. Convert Measurement Units Convert 20 feet to inches. Step 4 – Cross multiply and divide. Then add the correct unit. 20 feet 1 foot ? inches = 12 inches

22. Convert Measurement Units Convert 20 feet to inches. Step 4 – Cross multiply and divide. Then add the correct unit. 20 feet 1 foot ? inches = 12 inches 20 x 12 ÷ 1 = 240 inches

23. Convert Measurement Units 36 yards = ? feet Step 1 ?

24. Convert Measurement Units 36 yards = ? feet Step 1 ? 1 yard 3 feet Step 2 ?

25. Convert Measurement Units 36 yards = ? feet Step 2 ? 1 yard 36 yards 3 feet ? feet Step 3 ?

26. Convert Measurement Units 36 yards = ? feet Step 3 ? 1 yard 36 yards 3 feet = ? feet Step 4 ?

27. Convert Measurement Units 36 yards = ? feet Step 4 ? 1 yard 36 yards 3 feet = ? feet 3 x 36 = 108 ÷ 1 = 108 feet

28. Convert Measurement Units ¾ ton = ? pounds Do this on your own.

29. Convert Measurement Units ¾ ton = ? pounds 1 ton ¾ ton 2000 pounds = ? pounds 2000 3 6000 1 x 4 = 4 = 1500 ÷1 = 1500 pounds

30. Convert Measurement Units 1 ½ qt = ? pts Do this on your own.

31. Convert Measurement Units 1 ½ qt = ? pts 1 qt 1 ½ qts 2 pts = ? pts 2 3 6 1 x 2 = 2 = 3 ÷1 = 3 pts

32. Convert Measurement Units 15 qt = ? G Do this on your own.

33. Convert Measurement Units 15 qt = ? G 4 qts 15 qts 1 G = ? G 1 x 15 = 15 ÷ 4 = 3 ¾ G

34. Convert Measurement Units 100 ounces = ? pounds. Do this on your own.

35. Convert Measurement Units 100 ounces = ? pounds. 16 ounces 100 ounces 1 pound = ? pound 4 1 6 16 = 6 4 1 x 100 = 100 ÷ 16 =16 ) 100.00 -96 4

36. Convert Measurement Units Marco mixes ¼ cup of fertilizer with soil before planting each bulb. How many fluid ounces of fertilizer does he use for each bulb? Do this on your own.

37. Convert Measurement Units Marco mixes ¼ cup of fertilizer with soil before planting each bulb. How many fluid ounces of fertilizer does he use for each bulb? 1 cup ¼ cup 8 ounces = ? ounces 8 1 8 1 x 4 = 4 =2 ÷1 = 2 ounces

We can draw a bar diagram to solve this problem. Step 1 – Create a bar diagram and divide into sections matching the denominator of the fraction.

39. Convert Measurement Units Manual and his friends spent his birthday at the game center. He spent 4/7 of his money on go karts and now has $15 left. How much money did he spend on go karts? Step 2 – Divide the bar diagram by the numerator in the fraction. Amount spent on Amount not spent go karts on go karts ($15)

40. Convert Measurement Units Manual and his friends spent his birthday at the game center. He spent 4/7 of his money on go karts and now has $15 left. How much money did he spend on go karts? Step 3 – Determine how much each section is worth. Amount spent on Amount not spent go karts on go karts ($15) 5 5 555 5 5

41. Convert Measurement Units Manual and his friends spent his birthday at the game center. He spent 4/7 of his money on go karts and now has $15 left. How much money did he spend on go karts? Step 4 – Determine the unknown amount. Amount spent on Amount not spent go karts on go karts ($15) 5 5 555 5 5
