Step-by-Step Solution: 2/27 + 2/12

Step 1

Find the Least Common Denominator (LCD)

The denominators 27 and 12 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 108 (which is smaller than their product 27 ร— 12 = 324, keeping the calculation simpler).
LCD(27, 12) = 108
Step 2

Convert to Equivalent Fractions with Common Denominator 108

Multiply the numerator and denominator of 2/27 by 4, and multiply the numerator and denominator of 2/12 by 9 so both fractions share the common base 108.
2 ร— 4/27 ร— 4 = 8/108   and   2 ร— 9/12 ร— 9 = 18/108
Step 3

Add the Numerators

Now add the numerators (8 + 18 = 26) and keep the common denominator 108 unchanged.
8 + 18/108 = 26/108
Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 26 and 108, which is 2. Divide both the numerator and denominator by 2.
26 รท 2/108 รท 2 = 13/54
