Question

How do you evaluate `3/4 + 1/3 + 1/2`?

Answer 1

`=>19/12`

Explanation:

The fractions need to be expressed with a common denominator. There a few ways to obtain one, the easiest being to multiply all denominators together and multiplying each fraction by some expression equivalent to `1`, as this prevents the expression from changing.

`3/4 + 1/3 + 1/2`

`=3/4*3/3*2/2 + 1/3*4/4*2/2 + 1/2*4/4*3/3`

`=18/24 + 8/24 + 12/24`

`= 38/24`

`=19/12`
