Subtracting Mixed Numbers on a Number Line

The video tutorial explains how to subtract mixed numbers using a number line. It begins by introducing the concept of subtracting mixed numbers and demonstrates how to plot these numbers on a number line. The tutorial then covers finding a common denominator by partitioning each whole into equal parts. Finally, it shows how to calculate the difference between the numbers by counting the distance on the number line. The video concludes with a summary of the process.

What is the first step in using a number line to subtract mixed numbers?

• Multiply the numbers together.

• Convert the numbers to improper fractions.

• Draw a number line long enough to show both numbers.

• Find the sum of the numbers.

What does subtracting mixed numbers on a number line help us find?

• The quotient of the numbers.

• The difference between the numbers.

• The product of the numbers.

• The sum of the numbers.

Why do we need to partition each whole into equal parts?

• To make the numbers larger.

• To convert them into decimals.

• To simplify the fractions.

• To find a common denominator.

What is a common denominator for the fractions 1/6 and 2/3?

• 3

• 12

• 6

• 9

How is 2/3 represented when using sixths as a common denominator?

• 5/6

• 4/6

• 3/6

• 2/6

Where is 3 and one-sixth placed on the number line?

• At 3 and 1/2

• At 3 and 1/3

• At 3 and 1/6

• At 3 and 2/6

What is the first step in finding the distance between two numbers on a number line?

• Count up from the smaller number.

• Count down from the larger number.

• Multiply the numbers.

• Divide the numbers.

How many sixths are there between 1 and 2/3 and the next whole number?

• 4/6

• 1/6

• 2/6

• 3/6

What is the total distance in sixths between 1 and 2/3 and 3 and 1/6?

• 10/6

• 8/6

• 9/6

• 7/6

What is the final result of subtracting 1 and 2/3 from 3 and 1/6?

• 1 and 3/6

• 1 and 4/6

• 1 and 2/6

• 1 and 1/6
