<h3>Ratios and proportions</h3><h3 />
A ratio means a comparison of two different quantities while proportion is an equality of two ratios.
- AB = 5 in
- AC = 10 in
- AD = 4 in
- DC = 8 in
Ratio of AB to AC = 5 in : 10 in
= 5 / 10
= 1 / 2
= 1 : 2
Ratio of AD to DC = 4 in : 8 in
= 4 / 8
= 1 / 2
= 1 : 2
Therefore, the ratio of AB to AC and the ratio of AD to DC is 1 : 2 each respectively. They are equivalent ratios.

It is called the median :)
Answer:
C
Step-by-step explanation:
4.5 is 45 ÷ 10 and 81.1 is 811 ÷ 10 so that means that 4.5 × 81.1 = 45 ÷ 10 × 811 ÷ 10 = (45 × 81) ÷ 100. We know that 45 × 81 = 36,495 so we just have to divide that by 100 to get 364.95.
