Step-by-Step Solution: 3/24 + 8/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 24 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 24 ร— 13 = 312.
LCD(24, 13) = 312
Step 2

Convert to Equivalent Fractions with Common Denominator 312

Multiply the numerator and denominator of 3/24 by 13, and multiply the numerator and denominator of 8/13 by 24 so both fractions share the common base 312.
3 ร— 13/24 ร— 13 = 39/312   and   8 ร— 24/13 ร— 24 = 192/312
Step 3

Add the Numerators

Now add the numerators (39 + 192 = 231) and keep the common denominator 312 unchanged.
39 + 192/312 = 231/312
Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 231 and 312, which is 3. Divide both the numerator and denominator by 3.
231 รท 3/312 รท 3 = 77/104
Step 5
