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

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.
