Answer 2

Let's solve these proportions step by step:

1. 2.8 : 8 = x : 17.78

To find x, you can cross-multiply and then solve for x:

2.8 * 17.78 = 8 * x

49.924 = 8x

x = 49.924 / 8

x ≈ 6.24

2. 17.78 : 7 = x : 3.75

Cross-multiply and solve for x:

17.78 * 3.75 = 7 * x

66.675 = 7x

x = 66.675 / 7

x ≈ 9.525

3. 3.75 : 5 = x : 19.02

Cross-multiply and solve for x:

3.75 * 19.02 = 5 * x

71.325 = 5x

x = 71.325 / 5

x ≈ 14.265

4. 19.02 : 6 = x : 3.5

Cross-multiply and solve for x:

19.02 * 3.5 = 6 * x

66.57 = 6x

x = 66.57 / 6

x ≈ 11.095

5. 3.5 : 25 = x : 32.1

Cross-multiply and solve for x:

3.5 * 32.1 = 25 * x

112.35 = 25x

x = 112.35 / 25

x ≈ 4.494

6. 32.1 : 8 = x : 47.3

Cross-multiply and solve for x:

32.1 * 47.3 = 8 * x

1518.03 = 8x

x = 1518.03 / 8

x ≈ 189.75375

7. 47.3 : 11 = x : 30.96

Cross-multiply and solve for x:

47.3 * 30.96 = 11 * x

1464.768 = 11x

x = 1464.768 / 11

x ≈ 133.15

8. 6.15 : 5 = x : y

Since there is no value provided for y, you cannot solve for x without knowing the value of y.

If you have a specific value for y, you can apply the same cross-multiplication method to find x.
