Exact Answer

==================================================
Problem: What is 4/69 plus 2/13?
Formula / Expression: 4/69 + 2/13
Final Answer: 190/897
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 69 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 69 × 13 = 897.
Working: LCD(69, 13) = 897

Step 2: Convert to Equivalent Fractions with Common Denominator 897
Multiply the numerator and denominator of 4/69 by 13, and multiply the numerator and denominator of 2/13 by 69 so both fractions share the common base 897.
Working: 4 × 13/69 × 13 = 52/897 and 2 × 69/13 × 69 = 138/897

Step 3: Add the Numerators
Now add the numerators (52 + 138 = 190) and keep the common denominator 897 unchanged.
Working: 52 + 138/897 = 190/897

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 190 and 897 is 1, confirming that 190/897 cannot be reduced further—it is already in its simplest irreducible form.
Working: 190/897

Step 5: Decimal & Percentage Representation
Dividing the numerator 190 by denominator 897 produces a repeating decimal (approximately 0.211817, or 21.1817%).
Working: 190 ÷ 897 = 0.211817 (21.1817%)

Step-by-Step Solution: 4/69 + 2/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 69 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 69 × 13 = 897.

LCD(69, 13) = 897

Step 2

Convert to Equivalent Fractions with Common Denominator 897

Multiply the numerator and denominator of 4/69 by 13, and multiply the numerator and denominator of 2/13 by 69 so both fractions share the common base 897.

4 × 13/69 × 13 = 52/897 and 2 × 69/13 × 69 = 138/897

Step 3

Add the Numerators

Now add the numerators (52 + 138 = 190) and keep the common denominator 897 unchanged.

52 + 138/897 = 190/897

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 190 and 897 is 1, confirming that 190/897 cannot be reduced further—it is already in its simplest irreducible form.
