Answer key and explanations

  1. D. \(12\) items shared equally among \(3\) groups

    \(12\div3\) asks "how many in each group when \(12\) items are shared equally among \(3\) groups?" Each group gets \(4\) items.

  2. D. \(9\div3\)

    There are \(9\) circles total, divided into \(3\) equal groups. Each group has \(3\) circles, so \(9\div3=3\).

  3. D. \(3\)

    \(15\div5=3\). Sharing means dividing the total into equal groups.

  4. D. \(16\div4\)

    "How many groups of \(4\)" is a measurement division problem. Divide \(16\) by \(4\) to find the number of groups.

  5. A. \(2\times5=10\)

    Division and multiplication are inverse operations. Since \(2\times5=10\), then \(10\div2=5\).

  6. A. \(6\)

    \(18\div3=6\). Divide the total number of pencils by the number of boxes.

  7. A. \(20\div4\)

    Dividing equally among groups means the total is shared into equal parts. Use division.

  8. D. \(14\div2\)

    Measurement division finds how many groups. Divide the total by the group size.
