Building and decomposing fractions

Front

What is a fraction?

Back

A fraction represents a part of a whole and is written as a numerator (top number) over a denominator (bottom number). For example, in the fraction 1/2, 1 is the part and 2 is the whole.

Front

What does it mean to decompose a fraction?

Back

To decompose a fraction means to break it down into smaller fractions that add up to the original fraction. For example, 3/4 can be decomposed into 1/4 + 1/4 + 1/4.

Front

What is a unit fraction?

Back

A unit fraction is a fraction where the numerator is 1 and the denominator is a positive integer. For example, 1/3 and 1/5 are unit fractions.

How can you decompose 4/5?

Back

4/5 can be decomposed into 1/5 + 1/5 + 1/5 + 1/5 or 3/5 + 1/5.

Front

Which of the following is NOT a way to decompose 4/5? 1/5 + 1/5 + 1/5 + 1/5, 3/5 + 1/5, 2/5 + 2/5, 5/5 + 5/5 + 5/5 + 5/5

Back

5/5 + 5/5 + 5/5 + 5/5 is NOT a way to decompose 4/5.

Front

Write an equation that represents 4 1/4 as a sum of whole numbers and unit fractions.

Back

4 1/4 can be represented as 1 + 1 + 1 + 1 + 1/4.

What is the sum of 1/10 + 8/10?

Back

The sum is 9/10.

Front

Which of the following is NOT a way to decompose 9/10? 1/10 + 8/10, 4/10 + 5/10, 4/10 + 2/10 + 2/10, 4/10 + 3/10 + 1/10 + 1/10

Back

4/10 + 2/10 + 2/10 is NOT a way to decompose 9/10.

Which one shows 5/2 decomposed into smaller fractions? 1/2 + 1/2, 1/2 + 1/2 + 1/2 + 1/2 + 1/2, 2/5 + 2/5

Back

1/2 + 1/2 + 1/2 + 1/2 + 1/2 shows 5/2 decomposed into smaller fractions.
