If one piece of furniture was sold every 3/4 hour, how many pieces of furniture are sold in 3 hours

aleksklad [387]

Answer:

Two pieces of furniture.

Step-by-step explanation:

3 hours times 1 piece of furniture every 3/4 hours:

3 · $\frac{3}{4}$ = $\frac{3*3}{4}$ = $\frac{9}{4}$ = 2.25

Assuming that pieces of furniture cannot be sold in parts, 2 whole pieces of furniture will be sold in 3 hours.
