Answer 2

Finding the Fourth Number for Each Set of Three Numbers

To find the fourth number for each set of three numbers in order to form a proportion, we can use the given numbers and the concept of proportions.

1) Set: 8, 3, 24 To find the fourth number, we can set up the proportion: 8/3 = 24/x. Solving for x, we get x = 9.

2) Set: 100, 30, 48 Setting up the proportion: 100/30 = 48/x, we find that x = 16.

3) Set: 9, 7, 28 Using the proportion: 9/7 = 28/x, we can solve for x and find that x = 22.

4) Set: 3.5, 2.4, 4.2 Setting up the proportion: 3.5/2.4 = 4.2/x, we can solve for x and find that x ≈ 2.857 (rounded to three decimal places).

Therefore, the fourth numbers for each set are: 1) 9 2) 16 3) 22 4) Approximately 2.857

Please note that these calculations are based on the given numbers and the concept of proportions.
