Answer 2

Problem Analysis

We are given that four albums cost the same as eight notebooks, and we need to find the cost of one album if a notebook costs 12 rubles. We can solve this problem using different approaches.

Approach 1: Using Proportions

Let's assume the cost of one album is x rubles. According to the given information, four albums cost the same as eight notebooks. We can set up a proportion to solve for x:

4 albums / 8 notebooks = x rubles / 12 rubles

Simplifying the proportion:

4/8 = x/12

Cross-multiplying:

8x = 4 * 12

Solving for x:

8x = 48 x = 48 / 8 x = 6

Therefore, the cost of one album is 6 rubles.

Approach 2: Using Algebra

Let's assume the cost of one album is x rubles. According to the given information, four albums cost the same as eight notebooks. We can set up an equation to solve for x:

4x = 8 * 12

Simplifying the equation:

4x = 96

Dividing both sides by 4:

x = 96 / 4 x = 24

Therefore, the cost of one album is 24 rubles.

Approach 3: Using Division

We can also solve this problem by dividing the total cost of eight notebooks by four to find the cost of one album.

The total cost of eight notebooks is 8 * 12 = 96 rubles.

Dividing 96 rubles by 4, we get:

96 / 4 = 24

Therefore, the cost of one album is 24 rubles.

Conclusion

Using different approaches, we have determined that the cost of one album is 24 rubles if a notebook costs 12 rubles.
