2. Division and multiplication are inverse operations. So, you can use multiplication to check your answer to a division problem. A. Show the relationship between multiplication and division when there is no remainder.
Dividend ÷ Divisor = Quotient
Quotient × ___ = ____

Quotient x divisor = Dividend.

B. Show the relationship when there is a remainder.
Whole-Number Quotient × ___ + ___ = ____

Whole-Number Quotient × divisor  + Remainder = Dividend.

C. Apply the relationships to check division. Turn and Talk What are other ways you can check that your answer to a division problem is reasonable?

Check Understanding

Divide and check.

Question 1.  Question 2.  Question 3.
Reason A single-engine airplane with fuel can carry a maximum of 460 pounds in cargo. The pilot wants to load 5 boxes of equipment. If all the boxes have the same weight, what is the maximum weight each box can have? Attend to Precision Divide and check.

Question 4.  Question 5.  Question 6.  Question 7.  Question 8.
Use Structure When you divide a 4-digit number by a 1-digit number, how many digits can the whole-number quotient have? Explain how you know.

The whole number can still have 4 digits depending on the 1 digit. Because 1 digit number may or may not be multiple. Thereofore, it can have still 4 digits.

Question 9.
STEM The force of wind can change how fast an airplane flies. With a tailwind, a plane flies 2,340 miles in 5 hours. With a headwind, the plane flies the same distance in 6 hours. If the plane with the headwind flies the same distance every hour, how many miles does it fly each hour? Given,

The force of the wind can change how fast an airplane flies.

With a tailwind, a plane flies 2,340 miles in 5 hours.

With a headwind, the plane flies the same distance in 6 hours. Therefore, plane fly 390 miles each hour.
