Answer:
Option D
Step-by-step explanation:
We can multiply the first one by 2 to get 8:20
4:10 × 2 = 8:20
We can divide the second one by 2 to get 8:20
16:20 ÷ 2 = 8:20
We can divide the third one by 3 to get 8:20
24:60 ÷ 3 = 8:20
We can divide the fourth one by 3.5 to get 8:20
28:70 ÷ 3.5 = 8:20
This process of dividing and multiplying was finding equivalent ratios to answer the question.
