So basically we can simplify the fraction by finding the gcf which is the greatest common factor so 14/12 both have 2 in common we simplify that by dividing by 2 so 14÷2 is 7/6 is the fraction on the left hand side and d/48 is the fraction on the right hand side so to solve for d we have to divide 336/6 whixh equals 56 as tour answer. Hoped this helped!!

\(\frac{14}{12} = \frac{D}{48}\)

There is a method of solving proportions/ratios known as "Cross-Multiplying."

When \(\frac{a}{b} = \frac{c}{d}\)
\(ad=bc\) where the numbers diagonal from each other are multiplied together
(when you draw lines between the numbers you multiply, you get a "cross" or "X" shape)

Cross multiply
\((14)(48)=(12)(D)\)

Simplify
\(672=12D\)
\(\frac{672}{12} = \frac{12D}{12}\)
\(56=D\)

The answer is A. 56
