Understand the problem: Understand the problem. $\newline$ We need to find out how many rooms can be wired with $\frac{3}{4}$ of a roll of wire, knowing that each room requires $2$ rolls of wire. $\newline$ Calculation: None needed here.
Set up the equation: Set up the equation. $\newline$ To find the number of rooms that can be wired, divide the available rolls of wire by the rolls required per room. $\newline$ Calculation: $(\frac{3}{4}) \div 2$
Perform the division: Perform the division. $\newline$ $(\frac{3}{4}) \div 2 = (\frac{3}{4}) \times (\frac{1}{2}) = \frac{3}{8}$ $\newline$ This means $\frac{3}{8}$ of a room can be wired with $\frac{3}{4}$ of a roll of wire.
