Type 3/4, a mixed number like 1 1/2 (with a space), −2/5, 0.75 or a repeating decimal like 0.1(6).

Try:

13/6

In its simplest form

1
Write both numbers as fractions
- 1 1/2 is a mixed number: (1 × 2 + 1)/2 = 3/2
2
Find a common denominator
- The least common denominator (LCD) of 2 and 3 is 6.
- 3/2 = (3 × 3)/(2 × 3) = 9/6
- 2/3 = (2 × 2)/(3 × 2) = 4/6
3
Add the numerators
- 9/6 + 4/6 = (9 + 4)/6 = 13/6
4
Simplify
- 13/6 is already in its simplest form: the GCD of 13 and 6 is 1.
5
As a mixed number
- 13 ÷ 6 = 2 remainder 1, so 13/6 = 2 1/6
