4.4H Interpreting Remainders

Front

What is a remainder in division?

Back

A remainder is the amount left over after division when one number does not divide evenly into another.

Front

How do you calculate the number of items you can fit into a total time?

Back

Divide the total time by the time needed for each item. The quotient tells you how many items can fit, and the remainder shows how much time is left.

Front

If you have 120 minutes and each call takes 7 minutes, how many calls can you make?

Back

17 calls (120 ÷ 7 = 17 R1). You can make 17 calls and have 1 minute left over.

Front

What does it mean to drop the remainder in division?

Back

Dropping the remainder means ignoring it and only using the whole number part of the quotient.

Front

When might you use the remainder as part of the answer?

Back

You might use the remainder as part of the answer when the context of the problem requires it, such as when counting items.

Front

What is the formula to find the total number of items when given a total and a per-item amount?

Back

Total items = Total amount ÷ Amount per item.

Front

In the problem, '275 folders with 8 files each', how do you find the total number of files?

Back

Multiply 275 by 8 to find the total number of files.

Front

What is the importance of understanding remainders in real-life situations?

Back

Understanding remainders helps in making decisions based on incomplete divisions, such as scheduling or resource allocation.

Front

If a detective's file cabinet holds 275 folders and each folder holds 8 files, how many files are in one folder if one folder holds 3 files?

Back

That folder holds 3 files.

Front

What does it mean to round the quotient to the next greater whole number?
