Answer 2

Problem Analysis

We are given a rope with a length of 2 meters, and we need to find the length of each part after cutting off three-quarters of the rope.

Solution

To find the length of each part, we can follow these steps:

1. Calculate the length of the rope after cutting off three-quarters. 2. Divide the remaining length equally into three parts.

Let's calculate the length of each part step by step.

Step 1: Calculate the length of the remaining rope

To find the length of the remaining rope after cutting off three-quarters, we can use the following formula:

Remaining Length = Total Length - (Total Length * Three-Quarters)

Given that the total length is 2 meters, we can substitute the values into the formula:

Remaining Length = 2 - (2 * 3/4)

Simplifying the equation:

Remaining Length = 2 - 1.5

Remaining Length = 0.5 meters

Step 2: Divide the remaining length into three equal parts

To find the length of each part, we need to divide the remaining length equally into three parts. We can use the following formula:

Length of Each Part = Remaining Length / 3

Given that the remaining length is 0.5 meters, we can substitute the values into the formula:

Length of Each Part = 0.5 / 3

Simplifying the equation:

Length of Each Part = 0.1667 meters

Therefore, the length of each part of the rope is approximately 0.1667 meters.

Answer

The length of each part of the rope, after cutting off three-quarters of a 2-meter rope, is approximately 0.1667 meters.

Calculation Steps

1. Remaining Length = 2 - (2 * 3/4) = 0.5 meters 2. Length of Each Part = 0.5 / 3 = 0.1667 meters
