Answer:

a)1 : 4 and 5 : 20

Step-by-step explanation:

quantity on the left hand side is lesser than the quantity on the right hand side; it's a part of a whole, a small fraction.

Example of proportion ratios:

4 : 7

7 : 29

90 : 200

68 : 140

Example of non-prpotion ratios:

7 : 4

80 : 19

29 : 20
