Answer:
See below.
Step-by-step explanation:
1 2/3 + 2 1/4 + 1/6 cups.
this works out to 4 1/12 cups.
If each blue tile has 5 sides and you know you have 3 blue tiles you can multiply 5 by 3
5 x 3 = 15 sides
Next you know the total number of sides is 30 and you just figured out that your 3 blue tiles have a total of 15 sides so you can subtract 15 from 30 to find how many sides are left
30 - 15 = 15sides
Since you know that these are not blue tiles because in the question it stated that you have 3 blue tiles. These have to be sides for red tiles.
Each red tile have 3 sides so you can divide 15 by 3
15/3 = 5
There are 5 red tiles
You are the number 5
Convert to improper fraction: 2 5/12 = 29/12
Divide 29 by 12: 29/12 = 2.42
2.42 inches
