Answer 1

12:3=4 кг.
4*4 = 16 кг.
16-12=4.
ответ:4кг.

Answer 2

Problem Analysis

We are given the following information: - The box with grapes is 4 times lighter than the box with bananas. - The box with bananas weighs 12 kg more than the box with grapes.

We need to find the mass of the box with grapes.

Solution

Let's assume the mass of the box with grapes is x kg.

According to the given information: - The box with bananas weighs 12 kg more than the box with grapes, so the mass of the box with bananas is x + 12 kg. - The box with grapes is 4 times lighter than the box with bananas, so the mass of the box with grapes is (x + 12)/4 kg.

To find the mass of the box with grapes, we need to solve the equation:

(x + 12)/4 = x

Let's solve this equation to find the value of x.

Solving the Equation

To solve the equation, we can multiply both sides by 4 to eliminate the fraction:

4 * (x + 12)/4 = 4 * x

Simplifying the equation:

x + 12 = 4x

Now, let's isolate x by subtracting x from both sides:

12 = 4x - x

Simplifying further:

12 = 3x

Finally, divide both sides by 3 to solve for x:

x = 12/3 = 4

Therefore, the mass of the box with grapes is 4 kg.
