Understanding the Proportion

In order to find the value of x in the given proportion, we need to understand what it means for 7, 14, x, and 12 to be in proportion. When four numbers are in proportion, it means that the ratio of the first pair is equal to the ratio of the second pair. Mathematically, this can be represented as:

$\frac{7}{14} = \frac{x}{12}$

Finding the Value of x

To find the value of x, we can cross multiply the fractions:

$7 \times 12 = 14 \times x$

Solving this equation will give us the value of x:

$84 = 14x$

Dividing both sides by 14:

$x = 6$

Therefore, the value of x in the given proportion is 6. So, the correct answer is (b) 6.
