Answer:
Total length in inches - 126 inches
Total length in feet = 10.5 feet
Total length in yards = 3.503 yards
Explanation:
Given the dimension of the ribbon by the three friends given as;
Carol- 42 in.
Tino- 2.5 feet
Baxter- 1.5 yards
Express feet in inches
1 feet = 12inches
2.5 feet = 12*2.5
25feet = 30inches
Express yard in inches
1 yard = 36inches
1.5yard = 36(1.5)
1.5yard = 54inches
Take the sum in inches
Sum in inches = 42 + 30 + 54
Sum in inches = 126inches
Convert dimensions to feet
42inches to feet = 42/12 = 3.5 feet
1.5yards to feet = 1.5*3 = 4.5 feet
Take the sum in feet
Sum in feet = 3.5 + 4.5 + 2.5
Sum in feet = 10.5feet
Convert dimensions to yards
42inches to yards = 42/36 = 1.17 yards
2.5 feet to yards = 0.833yards
Take the sum in yards
Sum in yards = 1.5 + 1.17 + 0.833
Sum in yards = 3.503yards
