You have two pieces of rope. One piece is of rope is 98 feet and the other is 56 feet. You need to cut the rope into equal lengths with non left over. What is the greatest possible lenth you can cut the rope so all peices will be the same

Final answer:

The greatest length you can cut both ropes into so all pieces will be the same length with none left over is 14 feet, as it is the greatest common divisor of 98 feet and 56 feet.

Step-by-step explanation:

The problem you're describing involves finding the greatest common divisor (GCD) for the two lengths of rope. This will determine the longest possible length that you can cut both ropes into, with none left over.

To find the GCD, you can use the Euclidean algorithm which involves a series of divisions:

Divide the longer length (98 feet) by the shorter length (56 feet).

If there's no remainder, the divisor (56 feet) is the GCD.

If there is a remainder, divide the divisor (56 feet) by this remainder.

Continue this process, with the remainder each time becoming the new divisor until you get a remainder of 0. The last non-zero remainder is the GCD.

In this case:

98 ÷ 56 = 1 remainder 42

56 ÷ 42 = 1 remainder 14

42 ÷ 14 = 3 remainder 0

Since 14 divides into 42 without a remainder, 14 feet is the longest piece of rope you can cut both ropes into so all pieces will be the same length with none left over.

Answer:

14 feet

Step-by-step explanation:

We solve the above question by using the Greatest Common Factor method

We find the factors of 56 and 98

The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56

The factors of 98 are: 1, 2, 7, 14, 49, 98

Then the greatest common factor is 14.

Therefore, the greatest possible length you can cut the rope so all pieces will be the same is 14 feet
