Answer:

Step-by-step explanation:
Lets solve the first half.

Second one:

Now compare.....Not the same right??
So your answer is: 
Hope this helps :)
You need to implement the process of "flip-flop" and multiply which is where you flip the second fraction and multiply.

÷

⇒

×

Now you multiply across. 2×15=30 and 3×11=33
So now it is

To reduce to the lowest terms, find the GCF common factor
The GCF is 3
Divide both the numerator and denominator by 3

÷

=

Answer:
So from these given details will be right choice A. sure because given that 1 unit cube = 1 inch so from this result that 48 unit cubes = 48 cubic inches
