Answer 1

`450/90 = (450:90)/(90:90) = 5`

`330/110 = (330:110)/(110:110) = 3`

`120/80 = (120:40)/(80:40) = 3/2`

`930/30 = (930 :30)/(30:30) = 31`

`750/150 = (750 :150)/(150:150) = 5`

Answer 2

450/90 = 5

330/110 = 3 

120/80 = 3/2

930/30 = 31

750/150 = 5

Answer 3

450/90 = 5

330/110 = 3

120/80 = 3/2

930/30 = 31

750/150 = 5
