Final answer:
To find the ratio of green to white kitchen tiles, subtract the proportion of green tiles (1/3) from the total (3/3) to get the proportion of white tiles (2/3), resulting in a ratio of 1:2.
Step-by-step explanation:
If 1/3 of the kitchen tiles are green, this means that the remaining tiles must be white. Since the whole set of tiles can be thought of as 1 (or 3/3), if 1/3 are green, then 2/3 must be white. To express this relationship as a ratio, we can compare the number of green tiles to the number of white tiles.
The ratio of green to white tiles is simply 1:2. This is because there is 1 part green for every 2 parts white. Using examples from the reference, if we have five green cards and three yellow cards, the ratio of green to yellow cards is 5:3. Similarly, if green tiles represent 1/3 of the tiles, then by deducting this from the total (which is represented as 3/3), we determine that white tiles represent 2/3 of the tiles. Setting this information out as a ratio of green tiles to white tiles, we get 1:2.
