questions
Find the least common denominator (LCD), convert each fraction to that denominator, then add the numerators. For example: 1/3 + 1/4 → LCD is 12 → 4/12 + 3/12 = 7/12.
Multiply the numerators together and the denominators together, then simplify. Example: 2/3 × 3/4 = 6/12 = 1/2.
A mixed number combines a whole number and a proper fraction. For example, 7/4 as a mixed number is 1¾ (1 whole and 3/4 remaining).
