1) To solve the first proportion, we first convert mixed numbers to improper fractions
8 1/8 = 65/
2 1/2 = 5/2

Now we have
65/8 : 5/2 = 2 2/3 : x

Next we invert the second ratio
65/8 2/5 = 2 2/3 x

Multiplying the fractions
(65 2) / (8 5) = (8/3) *
130 / 40 = 8x/
13/4 = 8x/3

Cross multiply to solve for x
3 13 = 8x
39 = 32
x = 39/32

Therefore, the value of x is 39/32.

2) To solve the second proportion, we have
24 : 36 = x : 4

Cross multiply
24 4 = 36
96 = 36
x = 96 / 3
x = 2.67

So, the value of x is 2.67.

3) To solve the third proportion
x : 9 = 15 : 24

Cross multiply
x 24 = 9 1
24x = 13
x = 135 / 2
x = 5.625

Therefore, the value of x is 5.625.
