Alice is planting bushes around three sides of her yard. If each side is 16 feet long, and each bush fills 4 feet, how many bushes does she need to buy?
First find the total distance the bushes need to cover: 16 feet/side * 3 sides =

<output>48</output>
48 feet.
Then divide the total distance to fill by the distance each bush fills to find the number of bushes Alice needs to buy: 48 feet / 4 feet/bush = 
<gadget id="calculator">48/4</gadget>
