Question

Find the difference 2/3-2/4

Answer 1

`(1)/(6)`

Explanation:

1. You need the same denominator to subtract

2. You can do this by picking the least common multiple of both denominators or multiplying the denominators by each other. In this case, the LCM (least common multiple) and multiply 4*3 or 3*4 is the same thing: 12.

3. But, what you do to the denominator, you do to the numerator:

`(2*4=8)/(3*4=12) \\\\(2*3=6)/(4*3=12)` This leaves the fractions as
`(8)/(12) -(6)/(12) =(2)/(12)`.

4. When you subtract fractions, you don't subtract the denominator.

5. You can simplify this fraction by dividing the numerator and denominator by 6:
`(2/2)/(12/2) =(1)/(6)`
