Match each equation to one of the diagrams. \(12-m=4\) \(12=4\boldcdot m\) \(m-4=12\) \(\frac{m}{4}=12\) Four tape diagrams labeled A, B, C, and D. Tape diagram A has 2 bars of equal length. The top bar is labeled m. The bottom bar is partitioned into 2 parts labeled 12 and 4. Tape diagram B has 2 bars of equal length. The top bar is labeled 12. The bottom bar is partitioned into 2 parts labeled 4 and m. Tape diagram C has 2 bars of equal length. The top bar is labeled m. The bottom bar is partitioned into 4 parts labeled 12, 12, 12, and 12. Tape diagram D has 2 bars of equal length. The top bar is labeled 12. The bottom bar is partitioned into 4 parts labeled m, m, m, and m.

• \(12-m=4\) matches B

• \(12=4\boldcdot m\) matches D

• \(m-4=12\) matches A

• \(\frac{m}{4}=12\) matches C
