Question 1.
\nDetermine the following sums and differences. Show your work.
\na. 7 oz + 9 oz = ________ lb
\nb. 1 lb 5 oz + 11 oz = ________ lb
\nc. 1 lb \u2013 13 oz = ________ oz
\nd. 12 lb \u2013 4 oz = ________ lb ________ oz
\ne. 3 lb 9 oz + 9 oz = ________ lb ________ oz
\nf. 30 lb 9 oz + 9 lb 9 oz = ________ lb ________ oz
\ng. 25 lb 2 oz \u2013 14 oz = ________ lb ________ oz
\nh. 125 lb 2 oz \u2013 12 lb 3 oz = ________ lb ________ oz
\nAnswer:<\/p>\n

a. 7 oz + 9 oz = 1 lb
\nb. 1 lb 5 oz + 11 oz = 2 lb
\nc. 1 lb \u2013 13 oz = 3 oz
\nd. 12 lb \u2013 4 oz = 11 lb 12 oz
\ne. 3 lb 9 oz + 9 oz = 4 lb 2 oz
\nf. 30 lb 9 oz + 9 lb 9 oz = 40 lb 2 oz
\ng. 25 lb 2 oz \u2013 14 oz =\u00a0 24 lb 4 oz
\nh. 125 lb 2 oz \u2013 12 lb 3 oz = 112 lb 15 oz<\/p>\n

Question 2.
\nThe total weight of Sarah and Amanda\u2019s full backpacks is 27 pounds. Sarah\u2019s backpack weighs 15 pounds 9 ounces. How much does Amanda\u2019s backpack weigh?
\nAnswer:
\nGiven that, the weight of the both backpacks = 27 pounds
\nAlso given, the weight of Sarah’s bag = 15 pounds 9 ounces
\nNow,
\n27 – 15 lb 9\u00a0 oz = 11 lb 7 oz
\nTherefore, the weight of Amanda’s backpack = 11 pounds 7 ounces<\/p>\n

Question 3.
\nIn Emma\u2019s supply box, a pencil weighs 3 ounces. Her scissors weigh 3 ounces more than the pencil, and a bottle of glue weighs three times as much as the scissors. How much does the bottle of glue weigh in pounds and ounces?
\nAnswer:
\nGiven that,
\nThe weight of pencil = 3 ounces
\nAlso given the weight of scissors is 3 ounces more than the pencil
\n= 3 oz x 6
\n= 18 oz
\n1 pound = 16 ounces
\nSo, 1 pound 2 ounces
\nTherefore, the bottle of glue weighs 1 pound 2 ounces.<\/p>\n

Question 4.
\nUse the information in the chart about Jodi\u2019s school supplies to answer the following questions:
\n\"Engage
\na. On Mondays, Jodi packs only her laptop and supply case into her backpack. How much does her full backpack weigh?
\nb. On Tuesdays, Jodi brings her laptop, supply case, two notebooks, and two textbooks in her backpack. On Fridays, Jodi only packs her binder and supply case. How much less does Jodi\u2019s full backpack weigh on Friday than it does on Tuesday?
\nAnswer:
\na. The weight of backpack = 2 lb 14 oz
\nThe weight of laptop = 5 lb 12 oz
\nThe weight of supply case = 1 lb
\nTotal weight = 2 lb 14 oz + 5 lb 12 oz + 1 lb
\n= 8 lb 26 oz
\nIt is also written as 9 pounds 10 ounces
\nTherefore, the weight of\u00a0 Emma’s backpack = 9 pounds 10 ounces.<\/p>\n

b. On Tuesdays :
\nThe weight of laptop, supply case, two notebooks, and two textbooks
\n5 lb 12 oz + 1 lb + 11 lb + 11 lb + 3 lb 8 oz + 3 lb 8 oz = 12 lb 50 oz
\nIt is also written as 15 lb 2 oz.
\nOn Fridays ;
\nBinder and supply case
\n2 lb 5 oz + 1 lb = 3 lb 5 oz
\nNow,
\n15 lb 2 oz – 3 lb 5 oz =
\n11 lb 13 oz
\nTherefore, Jodi’s backpack weight is 11 pounds 13 ounces less on Friday than on Tuesdays<\/p>\n
