Answer 1

Problem Analysis

We are given that a group of students collected a total of 1260 kg of potatoes over a span of 2 days. On the second day, the students collected twice as many potatoes as they did on the first day. We need to determine how many kilograms of potatoes the students collected on the first day.

Solution

Let's assume that the number of kilograms of potatoes collected on the first day is x. Since the students collected twice as many potatoes on the second day, the number of kilograms of potatoes collected on the second day is 2x.

The total number of kilograms of potatoes collected over the two days is the sum of the potatoes collected on the first and second days, which is x + 2x = 3x.

We are given that the total number of kilograms of potatoes collected is 1260 kg. Therefore, we can set up the equation:

3x = 1260

To find the value of x, we can solve this equation.

Solving the Equation

To solve the equation 3x = 1260, we can divide both sides of the equation by 3:

3x / 3 = 1260 / 3

Simplifying, we get:

x = 420

Therefore, the students collected 420 kg of potatoes on the first day.

Answer

The students collected 420 kg of potatoes on the first day.
