To add fractions with unlike denominators, find the least common denominator (LCD) which is the least common multiple of the denominators. Rename the fractions using the LCD and add the numerators, reducing the final fraction if needed. The LCD of fractions with denominators of 5 and 4 is 20, as it is the lowest number that is a multiple of both 5 and 4.

1. Add Fractions With Unlike Denominators Example: To add fractions with different denominators, convert them so they have the same denominators. Find the least common denominator (LCD), which is the least common multiple of the denominators. Multiples of 5: 5, 10, 15, 20 Multiples of 4: 4, 8, 10, 12, 16, 20
