Step-by-step explanation
Divide both parts of the ratio 6:16 by the GCF 2. This will fully simplify the ratio.
The ratio 6:16 fully reduces to 3:8 which is one possible answer.
Triple both parts of that new ratio to get 9:24 which is another possible answer.
Return back to 3:8. Quadruple both parts to get another answer 12:32
There are infinitely many possible answers of the form 3k:8k where k is some nonzero real number. Each ratio mentioned fully reduces back to 3:8.
