Final answer:
The ratio of red tiles to all tiles is 60/143, which represents the proportion of red tiles against the total count of tiles.
Step-by-step explanation:
The question asked is: What is the ratio of red tiles to all tiles?
To find this, we count the total number of tiles first. There are 83 multicolored tiles and 60 plain red tiles. The total number of tiles is 83 (multicolored) + 60 (red) = 143 tiles.
Now, the ratio of red tiles to all tiles is the number of red tiles divided by the total number of tiles. So, the ratio is 60 (red tiles) / 143 (total tiles). This ratio cannot be simplified further and represents the proportion of red tiles to the total number of tiles on the floor.
