Answer 2

Given,

16:24 and 20: 30

To find,

If the given numbers are in proportion

Solution,

If, 16 : 24 and 20 : 30 are in proportion then

16:24::20:30

We know that if the given numbers are in proportion then the way to prove it is,

product of means = product of extremes

So,

24 × 20 = 16 × 30

480 = 480

Since the product of means = product of extremes, the given number are in proportion
