Answer key and explanations

D. \(15\)
"\(5\) times as many" is a multiplication signal. Her brother has \(5\) groups of Jada's \(3\) stickers: \(5 \times 3 = 15\) stickers.
D. \(24\)
"\(6\) times as many" tells us to multiply. Maya has \(6\) groups of Sam's \(4\) cards: \(6 \times 4 = 24\) trading cards.
D. \(6\)
The bar model shows the friend's bar split into \(3\) equal pieces, each the size of Elena's \(2\) books. So we multiply: \(3 \times 2 = 6\) books.
D. \(14\)
"\(2\) times as many" is a multiplication clue. Noah's sister has \(2\) groups of \(7\) crayons: \(2 \times 7 = 14\) crayons.
D. \(20\)
"\(4\) times as many" is a multiplication signal. Kai has \(4\) groups of Aisha's \(5\) fish: \(4 \times 5 = 20\) fish.
D. \(12\)
The bar model shows Diego's bar is twice as long as Miguel's---\(2\) groups of \(6\). So multiply: \(2 \times 6 = 12\) cars.
D. \(15\)
Two steps! Step 1: Grandma gave Lily \(4 \times 3 = 12\) more sheets. Step 2: Add what Lily already had: \(3 + 12 = 15\) sheets in all.
D. \(18\)
"\(2\) times as many" means multiply. The team scored \(2 \times 9 = 18\) points in the second quarter.
