Exact Answer

==================================================
Problem: What is 2/18 plus 8/49?
Formula / Expression: 2/18 + 8/49
Final Answer: 121/441
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 18 and 49 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 18 × 49 = 882.
Working: LCD(18, 49) = 882

Step 2: Convert to Equivalent Fractions with Common Denominator 882
Multiply the numerator and denominator of 2/18 by 49, and multiply the numerator and denominator of 8/49 by 18 so both fractions share the common base 882.
Working: 2 × 49/18 × 49 = 98/882 and 8 × 18/49 × 18 = 144/882

Step 3: Add the Numerators
Now add the numerators (98 + 144 = 242) and keep the common denominator 882 unchanged.
Working: 98 + 144/882 = 242/882

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 242 and 882, which is 2. Divide both the numerator and denominator by 2.
Working: 242 ÷ 2/882 ÷ 2 = 121/441

Step 5: Decimal & Percentage Representation
Dividing the numerator 121 by denominator 441 produces a repeating decimal (approximately 0.274376, or 27.4376%).
Working: 121 ÷ 441 = 0.274376 (27.4376%)

Step-by-Step Solution: 2/18 + 8/49

Step 1

Find the Least Common Denominator (LCD)

The denominators 18 and 49 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 18 × 49 = 882.

LCD(18, 49) = 882

Step 2

Convert to Equivalent Fractions with Common Denominator 882

Multiply the numerator and denominator of 2/18 by 49, and multiply the numerator and denominator of 8/49 by 18 so both fractions share the common base 882.

2 × 49/18 × 49 = 98/882 and 8 × 18/49 × 18 = 144/882

Step 3

Add the Numerators

Now add the numerators (98 + 144 = 242) and keep the common denominator 882 unchanged.

98 + 144/882 = 242/882

Step 4

Simplify the Fraction to Lowest Terms
