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 \dfrac{x}{14}=\dfrac{15}{21}\\\\\\\Rightarrow \dfrac{x}{14}=\dfrac{5}{7}\\\\\\\Rightarrow x=\dfrac{5}{7}\times14\\\\\Rightarrow x=10.

Thus, the required missing number is 10.

kobusy [5.1K]

Answer:

\boxed{x = 4}

Step-by-step explanation:

If ΔABC ~ ΔDEF

Then their sides must be proportional such that:

=> \frac{x}{3} = \frac{8}{6}

Cross Multiplying

=> x * 6 = 8*3

=> 6x = 24

Dividing both sides by 6

=> x = 4
