Essential Question<\/strong> How Can Patterns Help You Question Divide Multiples of 10?<\/p>\n

A.<\/strong>
\nA jet carries 18,000 passengers in 90 trips. The plane is full for each trip. How many passengers does the plane hold?
\n\"Envision
\nFind 18,000 \u00f7 90, the number of passengers on each trip.
\n\"Envision<\/p>\n

B.<\/strong>
\nThink of a basic fact to help you. 18 \u00f7 9 = 2
\nThink about patterns in place value and multiples of 10:
\n180 \u00f7 90 = 18 tens \u00f7 9 tens = 2
\n1,800 \u00f7 90 = 180 tens \u00f7 9 tens = 20
\n18,000 \u00f7 90 = 1,800 tens \u00f7 9 tens = 200
\nSo, the jet can hold 200 passengers.<\/p>\n

C.<\/strong>
\nOr, use multiplication.
\n90 \u00d7 2 = 180
\n90 \u00d7 20 = 1,800
\n90 \u00d7 200 = 18,000
\nSo 18,000 = 90 = 200
\nThe jet can hold 200 passengers.<\/p>\n

Think of multiplication to help you divide.

Question 30.
\nHigher-Order Thinking<\/strong> A baker uses 30 grams of sea salt for each batch of bread. Sea salt comes in an 18-kilogram package or an 800-gram package. Which size package should the baker buy so that no sea salt is left after all of the batches are made? Explain.
\n1 kilogram equals 1,000 grams
\n\"Envision
\nAnswer:<\/p>\n

Salt for one batch of bread = 30 grams<\/p>\n

For 800 grams package,<\/p>\n

Now,<\/p>\n

= 800\/30<\/p>\n

= 26 batches.<\/p>\n

For 18 kg salt,<\/p>\n

1 kg = 1000 grams<\/p>\n

18 kg = 18 x 1000 = 18000<\/p>\n

Now, 18000\/30<\/p>\n

\n500 – 365 = 135
\nThen divide the amount she needs by 5 weeks: 135 \u00f7 5 = 27
\nSelena needs to save $27 each week.
\nMy answer is reasonable because 365 + 27 + 27 + 27 + 27 + 27 = 500.<\/p>\n

Question 1.
\nThe football coach spent a total of $890 including $50 in tax for 35 shirts for the team. Each shirt cost the same amount. What was the price of one shirt before tax was added?
\nAnswer:<\/p>\n

Total cost = $890 including tax<\/p>\n

Total cost before tax added = $890 – $50 = $840<\/p>\n

\nA gymnast practices 6 days each week. She practices the same number of hours each day. If she practices a total of 120 hours in a 4-week period, how many hours each day does she practice?
\nAnswer:<\/p>\n

Number of days in the 4-week period = 4×7 = 28<\/p>\n

But, she practices only 6 days, Therefore, 6 days in a 4-week period = 6×4 = 24<\/p>\n

Total number of hours in 4-week period = 120<\/p>\n

Therefore, the number of hours each day she practices = 120 \u00f7 24 =5.<\/p>\n

Total earned = $420<\/p>\n

Number of days in each week = 5<\/p>\n

Total earned in each day = $420 \u00f7 5 = $84<\/p>\n

Total earned per hour = $12<\/p>\n

Therefore, the number of hours he works each day = $84 \u00f7$12 = 7.<\/p>\n

        Number of adults are needed to go on the seventh-grade trip = 225 \u00f7 15 = 15<\/p>\n

        Therefore, the number of adults are needed to go on the seventh-grade trip is 15.<\/p>\n

        Topic 5 Performance Task<\/h3>\n

        School Supplies<\/strong>
        \nA store had a sale on school supplies in August. The store manager recorded how many of several types of items were sold. Each of the same types of item costs the same amount. Use the information in the table to answer the questions.
        \n\"Envision<\/p>\n

        Question 1.
        \nBackpack sales totaled $1,200. How much did each backpack cost? Write an equation to model your work.
        \nAnswer:<\/p>\n

        Given,<\/p>\n

        Total sales = $1200<\/p>\n

        Total number of backpacks = 60<\/p>\n

        cost of each backpack = $1200 \u00f7 60 =\u00a0 $120 \u00f7 6 = $20.<\/p>\n

        Therefore, the cost of each backpack is $20.<\/p>\n

        Question 2.
        \nThe store sold 71 packages of pens. Use compatible numbers to estimate how many pens were in each package. Show your work.
        \nAnswer:<\/p>\n

        Given,<\/p>\n

        Number of packages = 71<\/p>\n

        Number of pens sold = 568<\/p>\n

        number of pens in each package is 568 \u00f7 71 = 8<\/p>\n

        Therefore, the number of pens in each package is 8<\/p>\n

        Question 3.
        \nThere were 16 pencils in each box. Olivia wants to find how many boxes of pencils were sold.
        \nPart A<\/strong>
        \nWhen Olivia divides 784 by 16, in which place should she write the first digit of the quotient? Tell how you know without dividing.
        \nPart B<\/strong>
        \nHow many boxes of pencils were sold?
        \nAnswer:<\/p>\n

        Number of pencils sold = 784<\/p>\n

        Number of pencils in each box = 16<\/p>\n

        Number of boxes of pencils sold = 784 \u00f7 16 = 49<\/p>\n

        Therefore, the number of boxes of pencils sold is 49.<\/p>\n

         <\/p>\n

        Question 4.
        \nThe store manager has ordered the calculators shown, but the shipment has been delayed.
        \nPart A<\/strong>
        \n\"Envision
        \nIf all the calculators ordered are sold, the total sales would be $2,014. Was the number of calculators ordered less than or greater than 100? How do you know without dividing?<\/p>\n

        Part B<\/strong>
        \nHow many calculators were ordered? Write an equation to model your work.
        \nAnswer:<\/p>\n

        Given,<\/p>\n

        Total sales = $2,014<\/p>\n

        Cost for each calculator = $19<\/p>\n

        Therefore number of calculators = $2,014 \u00f7 $19 = 106<\/p>\n

        So, the number of calculators ordered was 106 and it is greater than 100.<\/p>\n

        we can say it not by diving. 19 x 100 = 1900 and the total sales given is $2014. So it must be greater than 100.<\/p>\n

        Question 5.
        \nThe manager wants to order 408 more notebooks. The notebooks are shipped in packages of 12. He used partial quotients to find the number of packages to order. His work is shown on the right. Is his solution correct? Explain.
        \n\"Envision
        \nAnswer:<\/p>\n

        No. The model to find the number of packages to order is not correct.<\/p>\n

        Explanation:<\/p>\n

        408 \u00f7 12 = 34<\/p>\n

        But his work shown at right is showing the value is 40<\/p>\n

        So, it is not correct and the correct value is 34.<\/p>\n

        Question 6.
        \nAn additional 40 packages of paper were ordered at a total cost of $520. How much did each package of paper cost? Write an equation to model your work.
        \nAnswer:<\/p>\n

        Each package of paper cost $13<\/p>\n

        Because,<\/p>\n

        $520 \u00f7 40<\/p>\n

        $52 \u00f7 4 = $13.<\/p>\n","protected":false},"excerpt":{"rendered":"
