Kavi Shares the Pizzas 🍕
At the Owl Café, Kavi cuts pizzas. "Half of a half is a quarter — multiplying is taking a fraction OF a fraction, so the answer gets smaller," Kavi hoots. "But how many half-slices fit in 3 whole pizzas? Six! Dividing BY a fraction makes the answer bigger ⚡. To multiply, go straight across — top × top, bottom × bottom. To divide, keep, change, flip."

What your child will learn
1Multiplying is taking a fraction of a fractionTo find ½ × ⅓, first shade ⅓ of a bar, then take ½ of that shaded part. You are left with just 1 piece out of 6 — so ½ × ⅓ = 1/6. Taking a part of a part always lands on a smaller piece.

A peek inside
Work out 3/4 × 2/5 in simplest form.
tops: 3×2 = 6; bottoms: 4×5 = 20; so 6/20, then divide top and bottom by 2
Try this at home: Multiply (simplest form): 2/5 × 3/4 = __
