Subtracting Fractions of a Shape with Like Denominators

The video tutorial explains how to subtract fractions with like denominators by labeling shapes divided into equal parts. It begins with an introduction to fractions, covering numerators and denominators. The tutorial then provides two examples: one using a shape divided into fifths and another using a pizza divided into eighths. In both examples, the process of subtracting fractions is demonstrated by labeling and counting the remaining parts after some are removed. The video emphasizes that the denominator remains unchanged, as it represents the total number of equal parts the whole was initially divided into.

What does the numerator in a fraction represent?

• The shape of the parts

• The number of equal parts being considered

• The total number of parts a shape is divided into

• The size of each part

If a shape is divided into 5 equal parts and 1 part is removed, what fraction of the shape remains?

• 1/5

• 2/5

• 3/5

• 4/5

Why does the denominator remain unchanged when a part is removed from a fraction?

• Because the numerator changes

• Because the total number of parts remains the same

• Because the total number of parts changes

• Because the size of each part changes

In the pizza example, how many pieces are left after eating 2 out of 8 pieces?

• 6/8

• 7/8

• 5/8

• 4/8

What is the denominator of the remaining pizza fraction after 2 pieces are eaten?

• 10

• 2

• 8

• 6
