Three friends each have some ribbon. carol has 42 in of ribbon, tino has 2.5 feet of ribbon, and baxter has 1.5 yards of ribbon. express the total length of ribbon the three friends have in inches, feet, and yards

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
