dividing it by 1/4 is just a complicated way of saying dividing by 4 lol
so lets use the number 16. 16/4 is 4.

A)The new number is twice the original number. 4 is not 2 times bigger than 16
B)The new number is 4 times the original number. 4 is not 4 times bigger than 16
C)The new number is 1/4 of the original number. 4 IS 1/4 of 16.

The answer is C (:
