1) To solve for b in the equation 3/4 = b/11, we can cross multiply:
4b = 3 * 11
4b = 33
b = 33 / 4
b = 8.25

2) To solve for b in the equation b/5 = 6/15, we can cross multiply:
15b = 6 * 5
15b = 30
b = 30 / 15
b = 2

3) To solve for b in the equation 2/9 = 8/b, we can cross multiply:
2b = 9 * 8
2b = 72
b = 72 / 2
b = 36

4) To solve for b in the equation 10/b = 30/33, we can cross multiply:
10 * 33 = 30b
330 = 30b
b = 330 / 30
b = 11
