Answer:
48. 192
Explanation:
In order to get from 3/4 to 3/16, one way would be to divide by 4. Another way is to multiply 3/4 by 1/4.
You can test whether multiplying by 4 works by multiplying 3/4 by 4 and 3 by 4.
When 3/4 is multiplied by 4, it would equal 12/3 which will simplify to 3. This can be done again with 3*4=12.
So the answer would be 12*4 = 48 and 48*4 = 192.
