Answer: Hello!
first lets find our needed equations: these are:
1 feet is equivalent to 12 inches.
1 yard is equivalent to 36 inches
1 yard is equivalent to 3 feets
Carol has 42 inches, using that 12 inches is equivalent to 1 feet, then carol has 42/12 = 3.5 feets, and using that 1 yard is 36 inches, Carol has 42/36 = 1.17 yards.
Tino has 2.5 feets, using that 1 feet has 12 inches, then tino has 2.5*12 = 30 inches of ribon, and using that 1 yard is 3 feet, tino has 2.5/3 = 0.83 yards of ribbon.
baxter has 1.5 yards, then he has 1.5*36 = 54 inches or 1.5*3 = 4.5 feets of ribbon.
now you can add to get the total length of ribbon in inches, feet or yards:
inches = 42in + 30in + 54in = 126in
feet = 3.5ft + 2.5ft + 4.5ft = 10.5fy
yard = 1.17yd + 0.83yd + 1.5yd = 3.5yd
