Step 1

Find the Least Common Denominator (LCD)

The denominators 3 and 11 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 3 × 11 = 33.
LCD(3, 11) = 33
Step 2

Convert to Equivalent Fractions with Common Denominator 33

Multiply the numerator and denominator of 2/3 by 11, and multiply the numerator and denominator of 9/11 by 3 so both fractions share the common base 33.
2 × 11/3 × 11 = 22/33   and   9 × 3/11 × 3 = 27/33
Step 3

Add the Numerators

Now add the numerators (22 + 27 = 49) and keep the common denominator 33 unchanged.
22 + 27/33 = 49/33
