Question

Arrange the following in ascending order.

5. In the ratio 3 : 5, the consequent is 15. Find the antecedent.

Answer 1

The ratio a:b can be represented as a by b ie. a/b.

Here, a is called the antecedent and b is called the consequent.

Here, b = 15 (The consequent is equal to 15 according to the question).

So the required ratio is of the form a/15

And this ratio reduces to 3/5.

Therefore, a/15 = 3/5

Simplify and you will get: a = (15 x 3) / 5 = 45/5 = 9
