What does the denominator in a fraction tell us when drawing a model?

• The number of shaded boxes needed for the product

• The total number of boxes

Why is it necessary to draw one fraction model with rows and the other with columns?

• To simplify the multiplication process

• To differentiate between the two fractions

• It is not necessary; both models can be drawn using either rows or columns

• To ensure accurate representation of the multiplication
