What number could replace SYMBOL below?
\dfrac{A}{B} = \dfrac{SYMBOL}{D}
The fraction on the left represents A out of B slices of a rectangular pizza( 1 ).
What if we cut the pizza( 1 ) into D slices instead? How many slices would result in the same amount of pizza( 1 )?
We would need C slices.
\dfrac{A}{B} = \dfrac{C}{D} and so the answer is C.
Another way to get the answer is to multiply by \dfrac{M}{M}.
\dfrac{M}{M} = \dfrac{1}{1} = 1 so really we are multiplying by 1.
The final equation is: \dfrac{A}{B} \times \dfrac{M}{M} = \dfrac{C}{D} so our answer is C.

How many total slices would we need if we want the same amount of pizza( 1 ) in C slices?
We would need to cut the pizza( 1 ) into D slices.
\dfrac{A}{B} = \dfrac{C}{D} and so the answer is D.
