Question

Find the missing term in the proportion 21: 49:: 3: ?​

Answer 1

Answer:

7

Step-by-step explanation:

This is solved using the theorem that product on mean = product of extremes.

Let the missing term be 'a'.

Therefore;

         21 x a = 49 x 3

      => a = (49 x 3) / 21

      => a = 7
