Answer 2

Answer: The required missing number is 10.

Step-by-step explanation: We are given to find the missing number in the following proportion :

`?:14=15:21.`

Let the missing number be represented by x.

Then, according to the given information, we have

`x:14=15:21\\\\\Rightarrow (x)/(14)=(15)/(21)\\\\\\\Rightarrow (x)/(14)=(5)/(7)\\\\\\\Rightarrow x=(5)/(7)*14\\\\\Rightarrow x=10.`

Thus, the required missing number is 10.
