Answer 2

Problem Statement

A rope of length 27 meters is cut into a third. We need to find out how many meters of the rope were cut and how many meters of the rope are left.

Solution 1: Using Arithmetic Calculation

To find out how many meters of the rope were cut, we can calculate one-third of the length of the rope. Then, to find out how many meters of the rope are left, we can subtract the length that was cut from the original length.

Calculation: 1. Length of the rope = 27 meters 2. Length cut = (1/3) * 27 = 9 meters 3. Length left = 27 - 9 = 18 meters

So, 9 meters of the rope were cut, and 18 meters of the rope are left.

Solution 2: Using Fraction Calculation

We can also solve this problem using fractions. If we represent the length of the rope as a whole (1), then cutting it into a third means we are left with two-thirds of the original length.

Calculation: 1. Length of the rope = 27 meters 2. Length cut = (1/3) * 27 = 9 meters 3. Length left = 27 - 9 = 18 meters

So, 9 meters of the rope were cut, and 18 meters of the rope are left.

Both methods yield the same result: 9 meters of the rope were cut, and 18 meters of the rope are left.
