Step-by-Step Solution: 4/54 + 4/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 54 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 54 ร— 13 = 702.
LCD(54, 13) = 702
Step 2

Convert to Equivalent Fractions with Common Denominator 702

Multiply the numerator and denominator of 4/54 by 13, and multiply the numerator and denominator of 4/13 by 54 so both fractions share the common base 702.
4 ร— 13/54 ร— 13 = 52/702   and   4 ร— 54/13 ร— 54 = 216/702
Step 3

Add the Numerators

Now add the numerators (52 + 216 = 268) and keep the common denominator 702 unchanged.
52 + 216/702 = 268/702
Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 268 and 702, which is 2. Divide both the numerator and denominator by 2.
268 รท 2/702 รท 2 = 134/351
Step 5
