Three friends each have some ribbon. Carol has 54 inches of ribbon, Tino has 4.5 feet of ribbon, and Baxter has 5.5 yards of ribbon. Express the total length of ribbon the three friends have in inches, feet, and yards.

In terms of inches, 54 + 4.5*12 + 5.5*36

in feet, 54/12 + 4.5 + 5.5/3
in yards, 54/36 + 4.5/3 + 5.5

To find the total length of ribbon the three friends have, we need to convert all the measurements to the same unit.

Let's start by converting Tino's measurement from feet to inches. Since 1 foot is equal to 12 inches, we can multiply Tino's measurement by 12:

Tino's length in inches = 4.5 feet * 12 inches/foot = 54 inches.

Next, let's convert Baxter's measurement from yards to inches. Since 1 yard is equal to 3 feet and 1 foot is equal to 12 inches, we can multiply Baxter's measurement by 3 (to convert yards to feet) and then by 12 (to convert feet to inches):

Baxter's length in inches = 5.5 yards * 3 feet/yard * 12 inches/foot = 198 inches.

Now that we have converted all the measurements to inches, we can calculate the total length of ribbon:

Total length in inches = Carol's length + Tino's length + Baxter's length
= 54 inches + 54 inches + 198 inches
= 306 inches.

To express the total length of ribbon in feet, we need to divide the total length in inches by 12:

Total length in feet = 306 inches / 12 inches/foot
= 25.5 feet.

To express the total length of ribbon in yards, we need to divide the total length in inches by 36 (since 1 yard is equal to 36 inches):

Total length in yards = 306 inches / 36 inches/yard
= 8.5 yards.

Therefore, the three friends have a total length of 306 inches, 25.5 feet, and 8.5 yards of ribbon.
