  1. Sunshine State Standards MA.6.A.5.3 Estimate the results of computations with…decimals…and judge the reasonableness of the results. AlsoMA.6.A.1.1, MA.6.A.1.2. MA.6.A.1.3

  2. Think: The quotient shows that there is not enough to make 9 bags of slime that are 0.15 kg each. There is only enough for 8 bags. The decimal part of the quotient will not be used in the answer. Additional Example 1: Measurement ApplicationSuppose Mark wants to make bags of slime. If each bag of slime requires 0.15 kg of corn starch and he has 1.23 kg, how many bags of slime can he make? The question asks how many whole bags of slime can be made when the corn starch is divided into groups of 0.15 kg. 1.23 ÷ 0.15 = ? 1.23 ÷ 0.15 = 8.2 Mark can make 8 bags of slime.

  3. Check It Out: Example 1 Suppose Antonio wants to make bags of slime. If each bag of slime requires 0.15 kg of corn starch and he has 1.44 kg, how many bags of slime can he make? 1.44 ÷ 0.15 = 9.6 bags, but he can only make 9 whole bags

  4. __ 237 ÷ 36 = 6.583 Think: 6 rolls of film will not be enough to take every student’s picture. Mr. Jones will need to buy another roll of film The quotient must be rounded up to the next highest whole number. Additional Example 2: Photography Application There are 237 students in the seventh grade. If Mr. Jones buys rolls of film with 36 exposures each, how many rolls will he need to take every student’s picture? The question asks how many rolls are needed to take a picture of every one of the students. Mr. Jones will need 7 rolls of film.

  5. 342 ÷ 24 = 14.25 rolls. 14 rolls will not be enough so she needs 15 rolls. Check It Out: Example 2A There are 342 students in the seventh grade. If Ms. Tia buys rolls of film with 24 exposures each, how many rolls will she need to take every student’s picture?

  6. 43 ÷ 8 = 5.375. 5 packets is not enough, so she should order 6 packets. Check It Out: Example 2B The Spanish club has 43 members. Petra is ordering nametags that come in packets of 8. How many packets does she need for the entire Spanish club?

  7. Think: The question asks for an exact answer, so do not estimate. Use the entire quotient. 64.20 ÷ 15 = 4.28 Additional Example 3A: Application Gary has 64.20 meters of rope. If he cuts it into 15 equal pieces, how long is each piece? The question asks how long each piece will be when the rope is cut into 13 pieces. Each piece will be 4.28 meters long.

  8. Think: The question asks for an exact answer, so do not estimate. Use the entire quotient. 324 ÷ 50 = 6.48 Additional Example 3B: Application The marching band is going on a field trip to watch a college band perform. The bus costs $324 and is being split evenly among the 50 band members. How much must each band member pay? The question asks how much each band member will pay when the bust cost is split among 50 people. Each band member will pay $6.48.

  9. An exact answer is required. 64.20 ÷ 15 = 4.28 meters Check It Out: Example :3A Ethan has 64.20 meters of rope. If he cuts it into 15 equal pieces, how long is each piece?

  10. An exact answer is required. 324 ÷ 50 = $6.48 Check It Out: Example :3B The marching band is going on a field trip to watch a college band perform. The bus costs $324 and is being split evenly among the 50 band members. How much must each band member pay?
