Step-by-Step Solution: 1/52 + 3/21

Step 1

Find the Least Common Denominator (LCD)

The denominators 52 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 52 ร— 21 = 1092.
LCD(52, 21) = 1092
Step 2

Convert to Equivalent Fractions with Common Denominator 1092

Multiply the numerator and denominator of 1/52 by 21, and multiply the numerator and denominator of 3/21 by 52 so both fractions share the common base 1092.
1 ร— 21/52 ร— 21 = 21/1092   and   3 ร— 52/21 ร— 52 = 156/1092
Step 3

Add the Numerators

Now add the numerators (21 + 156 = 177) and keep the common denominator 1092 unchanged.
21 + 156/1092 = 177/1092
Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 177 and 1092, which is 3. Divide both the numerator and denominator by 3.
177 รท 3/1092 รท 3 = 59/364
Step 5
