D.4

Answer 1

12 is the correct answer

Answer 2

12

Explanation:

6 / .5 (same as 1/2)

or 6 X
`(2)/(1)   = 12`

Remember when we divide by a fraction we do the following

Keep it (the first number stays the same)

Change it (convert from a division problem to a multiplication problem)

Flip it (flip the fraction that we are dividing by over - this is called a reciprocal)
