Question

What is 4 and 3/4 - 1 and 1/3? The answer is one of these: 2 and 2/7, 2 and 2/12, 3 and 5/12, or 3 and 5/7

Answer 1

3 and 5/12

Explanation:

`4 (3)/(4) = (19)/(4)\\ \\1(1)/(3) = (4)/(3)`

`(19)/(4) - (4)/(3) \\\\(19(3) - 4(4))/(12) \\\\(57 - 16)/(12) \\\\(41)/(12) \\`

This fraction is equivalent to,

`3 and 5/12 = 3(5)/(12) = (12*3 + 5)/(12) = (41)/(12)`
