To add fractions with different denominators, find the least common denominator (LCD), convert each fraction, then add the numerators. For example:

1/3 + 1/4 = 4/12 + 3/12 = 7/12

Multiply the numerators together and the denominators together, then simplify:

2/3 × 3/4 = 6/12 = 1/2

Flip the second fraction (reciprocal) and multiply:

2/3 ÷ 4/5 = 2/3 × 5/4 = 10/12 = 5/6

Divide both numerator and denominator by their greatest common divisor (GCD). This calculator automatically simplifies results to lowest terms.

How do you add fractions with different denominators?

Find the LCD, convert each fraction, then add numerators. Example: 1/3 + 1/4 = 4/12 + 3/12 = 7/12.

How do you simplify a fraction?

Divide both numerator and denominator by their GCD. Example: 8/12 ÷ 4 = 2/3.

What is a mixed number?

A mixed number has a whole part and a fraction part, like 2 1/3. It equals 7/3 as an improper fraction.
