Ulleksa [173]

Answer:

1) Total length in inches = 162 inches

Step-by-step explanation:

express the total length of rope the three friends have in inches, feet, and yards.

2) Total length in Feet = 13.5 feet

3)Total length in yard = 4.5 yard

a) Total length in inches

Morgan has 42 inches of rope

Malcolm has 4 feet of rope

Convert to inches

1 foot = 12 inches

4 feet = 4 × 12 inches

= 48 inches

Roberto has 2 yards of rope

Convert to inches

1 yard = 36 inches

2 yards = 2 × 36 inches

= 72 inches

Hence, the total length of rope in inches

= (42 + 48 + 72)inches

= 162 inches

2) Total length in Feet

1 inch = 0.0833 feet

162 inches = 162 × 0.0833 feet

= 13.5 feet

2) Total length in yard

1 inch = 0.0278 yard

162 inches = 162 × 0.0278 yard

= 4.5 yard
