Exploring Unit Fractions Divided by Whole Numbers

In this video, Mr. J explains how to model the division of unit fractions by whole numbers using two examples: 1/3 divided by 5 and 1/6 divided by 4. He demonstrates the process of dividing a unit fraction into equal groups and calculating the resulting fraction. The video also provides links to additional resources for further learning on dividing fractions.

What is a unit fraction?

• A fraction where numerator and denominator are equal

• A fraction with a numerator of 0

• A fraction with a denominator of 1

• A fraction with a numerator of 1

What is the first step in dividing a unit fraction by a whole number?

• Subtract the fractions

• Add the fractions

• Divide the fraction into equal groups

• Multiply the fractions

How many equal groups do we divide 1/3 into when dividing by 5?

• 15 groups

• 10 groups

• 5 groups

• 3 groups

What is the purpose of selecting one group in the model?

• To find the numerator of the answer

• To determine the new denominator

• To simplify the fraction

• To increase the fraction's value

What common mistake is mentioned when finding the denominator in division of fractions?

• Counting only the pieces in one group

• Ignoring the total number of pieces

• Multiplying instead of adding

• Using the original denominator

What is the denominator of the answer when dividing 1/3 by 5?

• 3

• 15

• 20

• 5

How do we determine the total number of pieces in the model?

• By counting the filled pieces

• By multiplying the number of rows and columns

• By adding the number of groups

• By dividing the numerator by the denominator

Why is it important to understand the total number of pieces in the model?

• To determine the correct denominator

• To simplify the model

• To calculate the original fraction

• To find the correct numerator

How many pieces are in one group when dividing 1/6 by 4?

• 24 pieces

• 6 pieces

• 4 pieces

• 1 piece

What is the final answer when dividing 1/6 by 4?

• 1/4

• 1/6

• 4/6

• 1/24
