I'm actually really sick right now which is why I've been asking for help because I need to get a lot of math work completed because I have a TON of assignments that need to be done and I haven't really learned the material yet. >.<

16).....I think this is correct...

16/20  = ? / 45

4/ 5   =  ? /45       cross-multiply

45*4  = 5*?

180 = 5*?    divide by 5

36  =  ?

17)

?/10  = 20/25

?/10 =  4/5      cross-multiply

5?  =  4 * 10

5? = 40     divide both sides by 5

?  =  8

18)

?/4  =  6/3

?/4  = 2      multiply both sides by 2

?  = 8

19)

12/9  = ? / (33-9)

4/3  = ? / 24     cross-multiply

24*4  = 3* ?

96  = 3 * ?      divide both sides by 3

32  = ?
