These I need help on

I did the first page you asked for just now! :)

Step-by-step explanation:

20)  15 = 3r    R = 5

21)   k/2 = 6    K = 12

22)  3h = 27   H = 9

23)   j/3 = 4     J = 12

24)  6p = 30   P = 5

25)  n/10 = 40   N = 400

26)  h/4 = 15   H = 60

27)  9/s = 81   S = 9

28)  14 = 2c   C = 7

29)  26 = 13d   D = 2

30)  6 = m/3   M = 18

31)  7 = p/5   P= 35

32)  4w = 16   W = 4

33)  f/3 = 9   F = 27

34)  20 = 4x   X = 5

35)  3z = 36   Z = 12

36)  10 = j/6   J = 60
