• What are the basic components of a fraction?

  $Fraction =$$\frac{numerator}{denominator}$

  
• What does the denominator of a fraction represent?

  • The total number of equal parts the whole is divided into.

  
• If a fraction has a denominator of 5, what does this mean?

  The whole has been divided into 5 equal parts.

  
• How would you represent $\frac{3}{5}$ visually?


  Divide a whole into 5 equal parts and shade 3 of them.

  
• What does the numerator of a fraction represent?

  • The number of equal parts that are selected or shaded.

  
• What is the difference between $\frac{2}{4}$ and $\frac{2}{5}?$


  $\frac{2}{4}$ represents 2 out of 4 equal parts, while $\frac{2}{5}$ represents 2 out of 5 equal parts.

  
• How can you visually compare the fractions $\frac{2}{5}$ and $\frac{5}{5}?$


  • Divide two circles into 5 equal parts each.
  • Shade 2 parts in one circle to represent $\frac{2}{5}.$
  • Shade 5 parts in the other circle to represent $\frac{5}{5}.$
  • This visually demonstrates that $\frac{5}{5}$ is equivalent to the whole while $\frac{2}{5}$ is a smaller part of the whole.

  
• What does the numerator in a fraction represent?

  Number of parts we have
• What does the denominator in a fraction represent?

  Total number of equal parts
• If a pizza is cut into 8 slices and you have 3 slices, what fraction of the pizza do you have?

  $\frac{3}{8}$
• How do you set up the multiplication equation for $\frac{2}{3}$ and $\frac{1}{4}$?


  $\frac{2}{3} \times \frac{1}{4}$
