8 x a = 2 008

a = 2 008 : 8 = 251

__________

b : 7 = 824

b = 7 x 824 = 5 768

__________

c x 6 = 4 698

c = 4 698 : 6 = 783

____________

642 : d = 6

d = 642 : 6 = 107

____________

891 : e = 9

e = 891 : 9 = 99

_____________

f : 3 = 978

f = 3 x 978 = 2 934

_____________

8 x h = 416

h = 416 : 8 = 52

______________

i : 9 = 649 rest 5

i = 9 x 649 + 5 = 5 841 + 5 = 5 846

_______________

4 642 : j = 8 rest 2

4 642 = j x 8 + 2

j x 8 = 4 642 - 2 = 4 640

j = 4 640 : 8 = 580

_______________

2 822 : k = 9 rest 5

2 822 = 9 x k + 5

9 x k = 2 822 - 5 = 2 817

k = 2 817 : 9 = 313
