Answer 2

Given: x:26 :: 5:65

To find: The value of "x"

Solution: It is given,x:26 :: 5:65

According to the concept of means and extremes of the proportion, from the above equation, it is evident that x and 65 are extremes and 26 and 5 are the means.

When two ratios are in a proportion, it means that both the ratios are equal.

so, x/26 = 5/65

or,  x/26 = 1/13(in the reduced form)

or, x = 2

Hence, x is 2.
