Answer:

Step-by-step explanation:

Solution

Middle

The ratio of the shortest rope to the middle sized rope is

6/24 = 7/x                   Cross multiply

6*x = 24*7                   Find the right

6x = 168                      Divide by 6

6x/6 = 168/6

x = 28

Longest

The longest piece is found by using this ratio

6/24 = 10/x                 Cross Multiply

6x = 240                     Divide by 6

6x/6 = 240/6

x = 40

Total

The Total length of the rope is

24 + 28 + 40

Total 92
