A worker is tiling the floor of a rectangular room that is 12 feet by 15 feet. The tiles are square with side lengths $$1\frac13$$ feet. How many tiles are needed to cover the entire floor? Show your reasoning.

Multiple Select

A television screen has length $$16\frac12$$ inches, width $$w$$ inches, and area 462 square inches. Select **all** the equations that represent the relationship of the side lengths and area of the television.

• $$w\cdot462\ =\ 16\ \frac{1}{2}$$

• $$16\ \frac{1}{2}\ \cdot\ w\ =462$$

• $$462 \div 16\frac12 = w$$

• $$462 \div w= 16\frac12$$

• $$16\ \frac{1}{2}\ \cdot\ 462\ =\ w$$
