Question

By proportionality law , check whether 3:2 and 30:20 in proportion​

Answer 1

Answer:

Here the extremes are 3 and 20 and the means are 2 and 30. Product of extremes, ad = 3 × 20 = 60. Product of means, bc = 2 × 30 = 60. Thus by proportionality law, we find ad = bc and hence 3 : 2 and 30 : 20 are in proportion

Answer 2

Step-by-step explanation:

yes it is proportional because

3×10=30

2×10=20 (multiplying both by 10)
