Answer key and explanations

  1. C. \(24=6\times4\)

    When you see "times as many," think multiplication! "\(6\) times as many as \(4\)" becomes \(6 \times 4\), which equals \(24\). So choice C, \(24 = 6 \times 4\), is the equation that captures that idea.

  2. D. \(6\)

    "\(2\) times as many" is your signal to multiply. Sam has \(2\) groups of Maria's \(3\) stickers: \(2 \times 3 = 6\). So Sam has \(\mathbf{6}\) stickers.

  3. D. \(\text{Ava} = 4 \times 4\)

    Look at the picture: Ava's bar is split into \(4\) equal pieces, each the same length as Noah's bar. That's exactly what "\(4\) times as many" means---so we multiply: Ava \(= 4 \times 4 = 16\) cards.

  4. C. \(5 \times 3 = 15\)

    "\(3\) times as many" is a multiplication clue. Make \(3\) groups of the \(5\) green marbles: \(5 \times 3 = 15\) red marbles. Choice C is the equation that shows this.

  5. D. \(12\) is \(3\) times as many as \(4\)

    Read \(12 = 3 \times 4\) in words: "\(12\) equals \(3\) groups of \(4\)." That's the same as saying "\(12\) is \(3\) times as many as \(4\)." The other choices use more, plus, or less---those describe adding or subtracting, not multiplying.

  6. D. \(10\)

    "\(5\) times as many" means we multiply. Leo's sister reads \(5\) groups of \(2\) books, so \(5 \times 2 = 10\) books.

  7. D. \(18\)

    This is a two-step problem. Step 1: find Chen's cars: \(4 \times 6 = 24\). Step 2: "how many more" is a subtraction question, so \(24 - 6 = 18\). Chen has \(\mathbf{18}\) more cars than Diego.

  8. D. \(16\)

    "\(2\) times as many" is a multiplication signal. Max bakes \(2\) groups of Mia's \(8\) cookies: \(8 \times 2 = 16\) cookies.
