Solving equations with fractions can you check these?

Question

16) 51m = 3
i got: m =17

18) 5j = 50
i got :
j = 10

20) 1/4c = 9
i got:
c= 36

22)
11e = 15
i got:
e = 1.363636363

24) 19 = 1/6q
i got:
q = 114

26)
z/4 -2 = 10
i got:
z = 48

28) 5/6n -2 = 8
i got :
n = 12

30) j/7 - 10 = 32
i got:
j =294

can you check if these are right?

Answer 1

16) 51m = 3
i got: m =17

I get m = 3/51 = 1/17

Answer 2

18) 5j = 50
i got :
j = 10
yes

20) 1/4c = 9
i got:
c= 36
ok if you really mean (1/4) c = 9

22)
11e = 15
i got:
e = 1.363636363
or just 15/11

24) 19 = 1/6q
i got:
q = 114
again ok if 19 = (1/6) q or q/6

26)
z/4 -2 = 10
i got:
z = 48
Please use parentheses so I can tell what is on top
ok if you mean (z/4) -2 = 10
then z/4 = 12
z = 48

28) 5/6n -2 = 8
i got :
n = 12
yes with my usual comment

30) j/7 - 10 = 32
i got:
j =294 yes
