What is 2/18 plus 2/14? (Answer: 16/63)

Exact Answer

==================================================
Problem: What is 2/18 plus 2/14?
Formula / Expression: 2/18 + 2/14
Final Answer: 16/63
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 18 and 14 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 126 (which is smaller than their product 18 × 14 = 252, keeping the calculation simpler).
Working: LCD(18, 14) = 126

Step 2: Convert to Equivalent Fractions with Common Denominator 126
Multiply the numerator and denominator of 2/18 by 7, and multiply the numerator and denominator of 2/14 by 9 so both fractions share the common base 126.
Working: 2 × 7/18 × 7 = 14/126 and 2 × 9/14 × 9 = 18/126

Step 3: Add the Numerators
Now add the numerators (14 + 18 = 32) and keep the common denominator 126 unchanged.
Working: 14 + 18/126 = 32/126

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 32 and 126, which is 2. Divide both the numerator and denominator by 2.
Working: 32 ÷ 2/126 ÷ 2 = 16/63

Step 5: Decimal & Percentage Representation
Dividing the numerator 16 by denominator 63 produces a repeating decimal (approximately 0.253968, or 25.3968%).
Working: 16 ÷ 63 = 0.253968 (25.3968%)

Key Values:
- Simplified Fraction: 16/63
- Mixed Number Form: 16/63
- Decimal Value: 0.253968
- Percentage: 25.3968%

Step-by-Step Solution: 2/18 + 2/14

Step 1

Find the Least Common Denominator (LCD)

The denominators 18 and 14 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 126 (which is smaller than their product 18 × 14 = 252, keeping the calculation simpler).

LCD(18, 14) = 126

Step 2

Convert to Equivalent Fractions with Common Denominator 126

Multiply the numerator and denominator of 2/18 by 7, and multiply the numerator and denominator of 2/14 by 9 so both fractions share the common base 126.

2 × 7/18 × 7 = 14/126 and 2 × 9/14 × 9 = 18/126

Step 3

Add the Numerators

Now add the numerators (14 + 18 = 32) and keep the common denominator 126 unchanged.

14 + 18/126 = 32/126

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 32 and 126, which is 2. Divide both the numerator and denominator by 2.

32 ÷ 2/126 ÷ 2 = 16/63

Step 5

Decimal & Percentage Representation

Dividing the numerator 16 by denominator 63 produces a repeating decimal (approximately 0.253968, or 25.3968%).

16 ÷ 63 = 0.253968 (25.3968%)
