Exact Answer

==================================================
Problem: What is 2/15 plus 8/49?
Formula / Expression: 2/15 + 8/49
Final Answer: 218/735
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 15 and 49 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 15 × 49 = 735.
Working: LCD(15, 49) = 735

Step 2: Convert to Equivalent Fractions with Common Denominator 735
Multiply the numerator and denominator of 2/15 by 49, and multiply the numerator and denominator of 8/49 by 15 so both fractions share the common base 735.
Working: 2 × 49/15 × 49 = 98/735 and 8 × 15/49 × 15 = 120/735

Step 3: Add the Numerators
Now add the numerators (98 + 120 = 218) and keep the common denominator 735 unchanged.
Working: 98 + 120/735 = 218/735

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 218 and 735 is 1, confirming that 218/735 cannot be reduced further—it is already in its simplest irreducible form.
Working: 218/735

Step 5: Decimal & Percentage Representation
Dividing the numerator 218 by denominator 735 produces a repeating decimal (approximately 0.296599, or 29.6599%).
Working: 218 ÷ 735 = 0.296599 (29.6599%)

Step-by-Step Solution: 2/15 + 8/49

Step 1

Find the Least Common Denominator (LCD)

The denominators 15 and 49 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 15 × 49 = 735.

LCD(15, 49) = 735

Step 2

Convert to Equivalent Fractions with Common Denominator 735

Multiply the numerator and denominator of 2/15 by 49, and multiply the numerator and denominator of 8/49 by 15 so both fractions share the common base 735.

2 × 49/15 × 49 = 98/735 and 8 × 15/49 × 15 = 120/735

Step 3

Add the Numerators

Now add the numerators (98 + 120 = 218) and keep the common denominator 735 unchanged.

98 + 120/735 = 218/735

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 218 and 735 is 1, confirming that 218/735 cannot be reduced further—it is already in its simplest irreducible form.
