Answer:

Step-by-step explanation:

Given:

Roy and Ai sell newspapers on weekends.

For every 3 newspapers that Roy sells, Ai sells 5.

Roy sold 15 newspapers.

Asked:

How many newspapers did Ai sell?

Illustration:

Let's use the given information to find the number of newspapers Ai sold.

Given that for every 3 newspapers Roy sells, Ai sells 5, we can set up a proportion:

Number of newspapers sold by Roy

3

=

Number of newspapers sold by Ai

5

3

Number of newspapers sold by Roy

​

=

5

Number of newspapers sold by Ai

​

Since Roy sold 15 newspapers, we can substitute this value:

15

3

=

Number of newspapers sold by Ai

5

3

15

​

=

5

Number of newspapers sold by Ai

​

Now, solve for the number of newspapers sold by Ai:

15

3

=

Number of newspapers sold by Ai

5

15

​

=

5

Number of newspapers sold by Ai

5×5=Number of newspapers sold by Ai

25

=

Number of newspapers sold by Ai

25=Number of newspapers sold by Ai

Therefore, Ai sold 25 newspapers.

Answer:

Given:

- Roy sold 15 newspapers.

- Roy and Ai sell newspapers together in a ratio of 3:5.

Asked:

- How many newspapers did Ai sell?

To illustrate the problem, let's assume that Roy and Ai sell newspapers in bundles of 3 and 5 respectively. Since the ratio of their sales is 3:5, we can represent Roy's sales as 3x and Ai's sales as 5x, where x is a common multiplier.

Given that Roy sold 15 newspapers, we can set up the equation:

3x = 15

To find the value of x, we divide both sides of the equation by 3:

x = 15 / 3

x = 5

Now that we know the value of x, we can determine Ai's sales by substituting it into the equation for Ai's sales:

5x = 5 * 5

5x = 25

Therefore, Ai sold 25 newspapers.
