In his new living room, Kirk installed carpeting on 1/2 of the floor and tile on another 1/4 of the floor. What fraction of the floor is now covered by either carpet or tile?

• Kytten: To find the total amount of floor covered add the amount of carpeting and tiling together. So 1/2 = 2/4, then 1/4 + 2/4 = (1 + 2) / 4 = 3/4. 3/4 of Captain Kirk's floor is covered.
