Which of these is not equal to 1/4?

A. 2/4

B. 4/16

C. 25%

D. 0.25

E. 5/20

I believe it's E it cant be 2/4 because 2/4 equals to 1/2

2/4

All the others cancel down to 1/4

4/16 If you divide both sides by 4 you get 1/4

25% is one quarter as a percentage so it's 25/100 which is 1/4

0.25 is also 25/100 so that is again 1/4

And 5/20 if you divide the top and bitten by five you get 1/4
