Answer:
3:5, 12:20
Step-by-step explanation:
A ratio is basically just a fraction. Therefore, 6:10 is just 6/10, or 3/5, or 3:5. It's the same thing as a fraction, just with a colon.
Thus, all you need is two equivalent fractions to 6/10. Examples are 3/5, 12/20, 30/50, etc. After you find the fractions, you just need to put them back into ratio form, so 3:5, 12:20, 30:50, etc.
