What value of x will make this proportion true? a. 7 b. 18 c. 24 d. 28 42 3 4 = 14 x 1 2

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
