Question

The ratio of 15 and a number.

Answer 1

15:x or 15 to x

Explanation:

it depends on what the question is asking, so if they want you to fill in a number, you could replace x with any number you'd like. but its probably a word problem they want you to put as numbers, so bc you dont know what 'a number' is, you can pick a variable such as x to replace it with.

hope this helps :)

15 to 20
