1/4 plus 5/3

To solve this, we need to find a common denominator for 4 and 3, which is 12. So we will rewrite 1/4 and 5/3 with 12 as their denominator.

1/4 can be rewritten as 3/12 (multiply the numerator and denominator by 3).
5/3 can be rewritten as 20/12 (multiply the numerator and denominator by 4).

Now we can add the fractions: 3/12 + 20/12 = 23/12.

Therefore, 1/4 plus 5/3 equals 23/12.
