Problem Analysis

We are given that a journal announced a contest for children's drawings, and one-ninth of its subscribers participated in the contest. We need to determine the total number of subscribers if the journal received drawings from 10,000 children.

Solution

Let's assume the total number of subscribers to the journal is x.

According to the problem statement, one-ninth of the subscribers participated in the contest. Therefore, the number of subscribers who participated in the contest is x/9.

We are also given that the journal received drawings from 10,000 children. Therefore, the number of participants in the contest is equal to 10,000.

Using this information, we can set up the following equation:

x/9 = 10,000

To find the value of x, we can multiply both sides of the equation by 9:

x = 10,000 * 9

Simplifying the equation, we get:

x = 90,000

Therefore, the journal has a total of 90,000 subscribers.

Answer

The journal has 90,000 subscribers.
