Answer 1

Hello !


Here is your answer !


the given digits will be in proportion if the product of the mean is equal to the product of the extreme

Product of extremes = 49 × 2 = 98


Product of means = 14 × 7 = 98


So it it in proportion

Hope it helps

Answer 2

Solution :

************************************

We know that ,

If ad = bc then a , b , c , d are

in proportion .

********†***************************

Here ,

a = 2 , b = 7 , c = 14 , d = 49

Now ,

a × d = 2 × 49 = 98

b × c = 7 × 14 = 98

Therefore ,

ad = bc

So , 2 , 7 , 14 , 49 are in

Proportion.
