What is 2/14 plus 9/22? (Answer: 85/154)

Exact Answer

==================================================
Problem: What is 2/14 plus 9/22?
Formula / Expression: 2/14 + 9/22
Final Answer: 85/154
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 14 and 22 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 154 (which is smaller than their product 14 × 22 = 308, keeping the calculation simpler).
Working: LCD(14, 22) = 154

Step 2: Convert to Equivalent Fractions with Common Denominator 154
Multiply the numerator and denominator of 2/14 by 11, and multiply the numerator and denominator of 9/22 by 7 so both fractions share the common base 154.
Working: 2 × 11/14 × 11 = 22/154 and 9 × 7/22 × 7 = 63/154

Step 3: Add the Numerators
Now add the numerators (22 + 63 = 85) and keep the common denominator 154 unchanged.
Working: 22 + 63/154 = 85/154

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 85 and 154 is 1, confirming that 85/154 cannot be reduced further—it is already in its simplest irreducible form.
Working: 85/154

Step 5: Decimal & Percentage Representation
Dividing the numerator 85 by denominator 154 produces a repeating decimal (approximately 0.551948, or 55.1948%).
Working: 85 ÷ 154 = 0.551948 (55.1948%)

Key Values:
- Simplified Fraction: 85/154
- Mixed Number Form: 85/154
- Decimal Value: 0.551948
- Percentage: 55.1948%

Step-by-Step Solution: 2/14 + 9/22

Step 1

Find the Least Common Denominator (LCD)

The denominators 14 and 22 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 154 (which is smaller than their product 14 × 22 = 308, keeping the calculation simpler).

LCD(14, 22) = 154

Step 2

Convert to Equivalent Fractions with Common Denominator 154

Multiply the numerator and denominator of 2/14 by 11, and multiply the numerator and denominator of 9/22 by 7 so both fractions share the common base 154.

2 × 11/14 × 11 = 22/154 and 9 × 7/22 × 7 = 63/154

Step 3

Add the Numerators

Now add the numerators (22 + 63 = 85) and keep the common denominator 154 unchanged.

22 + 63/154 = 85/154

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 85 and 154 is 1, confirming that 85/154 cannot be reduced further—it is already in its simplest irreducible form.
