Question

The ratio of students who own a dog and students who don't is 2:3. There are 25 total students in the class. How many students own a dog?​

Answer 1

10

Explanation:

So we know that the ratio is 2:3. This means that 2/5 of the class owns a dog because the remaining "3" take up 3/5.

2/5 of the class own a dog. There are 25 students in the class.

25/5 = 5

5*2 = 10.

Ten (10) students own a dog.

For these questions, all you need to do is just add the two or more ratio numbers together. Then divide the total amount of things there are by that number. After that just multiply the result by the number of units (or parts or sections) and you get your answer.

Answer 2

10 students

Explanation:

2+3=5u ( total ratio )

5u=25

1u=25÷5=5

2u (own dogs)= 5x2=10

Hope this helps! Thanks.
