## Ready when they can

- Solve: 'A recipe needs 2 1/3 cups of flour; you want to make 1 1/2 batches. How much flour?'
- Draw a fraction model to represent and solve a multiplication word problem
- Check the reasonableness of a fraction product in context using estimation

## Lesson: Fraction multiplication in real life

You already know how to multiply fractions and mixed numbers. Now you will use that skill on real problems: recipes, materials, distances. The trick is spotting when a problem is really asking you to multiply. Watch for the word 'of', like '2/3 of a recipe' or 'half of a board'.

*(drawing: The shaded part shows 2/3 of the recipe. To find the amount for 2/3, you multiply 2/3 by the full recipe amount.)*

**Example.** A recipe needs 2 1/3 cups of flour for one batch. You want to make 1 1/2 batches. First, change both mixed numbers to fractions: 2 1/3 = 7/3, and 1 1/2 = 3/2. Multiply: 7/3 x 3/2 = 21/6 = 3 1/2. Check it with an estimate: 2 1/3 is close to 2, and 1 1/2 is close to 1.5, so 2 x 1.5 = 3. Your exact answer, 3 1/2, is close to that estimate, so it makes sense. You need 3 1/2 cups of flour.

**Tip.** Before you multiply, round the mixed numbers to the nearest whole number and multiply those. If your exact answer is close to that rounded guess, you probably did it right.

**Recap.** To solve a real fraction problem, turn mixed numbers into fractions, multiply, then check your answer with a quick estimate.
