We are given proportion as 14/x = 1/2

So first step is to get rid off 2 from denominator,so we multipy both sides by 2

2(14/x) =2(1/2)

28/x =1

Next step is to get rid off x from denominator ,so we multiply both sides  of the equation by x

x(28/x) =x(1)

28x/x =x

28 =x

Hence we get value of x =28

So answer is choice d) 28
