What you’ll learn
Interpret fraction division visually.
Key idea
A count of serving-sized pieces is total amount divided by serving size.
A new cell denominator requires scaling the shaded numerator too; the one-cell serving count is not the original numerator.
Worked example
Enter the exact value or ordered values in the format requested below.
A jug holds 3/4 cup. A bar is partitioned into 8 equal 1/8-cup cells. Each serving is one cell. Enter the division equation counting servings, including its quotient.
- Rewrite the available 3/4 cup as 6/8 cup.
- Each shaded cell is one serving, so (3/4)÷(1/8)=6.
Answer: (3/4)÷(1/8)=6
Quick Check
Choose which candidate representation satisfies the requirements of 'Interpret fraction division visually' and justify the choice.
A bar has 18 equal 1/18-cup cells. Which model represents 4/6 cup and groups it into one-cell servings?
