To use base-ten blocks for dividing 2.16 by 3, first represent 2.16 using the blocks: two whole blocks for 2, one long block for 0.1, and six unit blocks for 0.06. Next, divide each type of block by 3: each whole block becomes two-thirds of a whole block, the long block becomes one-third of a long block, and the unit blocks can be grouped into sets of two to find how many fit into the division. Finally, combine the results to express the quotient, showing that 2.16 divided by 3 equals approximately 0.72.
