1/4 x 4/1 1 x 4= 4 4 X 1= 4 1/4 X 4/1= 4/4 = 1 The answer is 1.

(1/4) / (1/16) = (1/4) * (16/1) = 16/4 = 4/1 = 4

(1/4) / (1/16) = (1/4) * (16/1) = 16/4 = 4/1 = 4

(1/4) / (1/16) = (1/4) * (16/1) = 16/4 = 4/1 = 4

(1/4) / (1/16) = (1/4) * (16/1) = 16/4 = 4/1 = 4

four 1/4's make up 1, for example: 1/4+1/4=2/4 2/4+1/4=3/4 and 3/4+1/4=4/4

4/4 is equivalent to 1

1/4 divided by 1/4 is just another form of 1

so,

1/4//1/4

is the same as saying,

1/4 * 4/1

= 4/4 or 1

------------

1/4 divided by 1/4 = 1

1/4 x 1/4 = 1/16

1/4 + 1/4 = 1/2

1/4 - 1/4 = 0
