What is 5/14 plus 1/2? (Answer: 6/7)

Exact Answer

==================================================
Problem: What is 5/14 plus 1/2?
Formula / Expression: 5/14 + 1/2
Final Answer: 6/7
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 14 is an exact multiple of 2 (2 × 7 = 14). The Least Common Denominator (LCD) is simply 14, meaning we only need to scale one fraction.
Working: LCD(14, 2) = 14

Step 2: Convert to Equivalent Fractions with Common Denominator 14
Multiply the numerator and denominator of 5/14 by 1, and multiply the numerator and denominator of 1/2 by 7 so both fractions share the common base 14.
Working: 5 × 1/14 × 1 = 5/14 and 1 × 7/2 × 7 = 7/14

Step 3: Add the Numerators
Now add the numerators (5 + 7 = 12) and keep the common denominator 14 unchanged.
Working: 5 + 7/14 = 12/14

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 12 and 14, which is 2. Divide both the numerator and denominator by 2.
Working: 12 ÷ 2/14 ÷ 2 = 6/7

Step 5: Decimal & Percentage Representation
Dividing the numerator 6 by denominator 7 produces a repeating decimal (approximately 0.857143, or 85.7143%).
Working: 6 ÷ 7 = 0.857143 (85.7143%)

Key Values:
- Simplified Fraction: 6/7
- Mixed Number Form: 6/7
- Decimal Value: 0.857143
- Percentage: 85.7143%

Step 1

Find the Least Common Denominator (LCD)

Notice that 14 is an exact multiple of 2 (2 × 7 = 14). The Least Common Denominator (LCD) is simply 14, meaning we only need to scale one fraction.

LCD(14, 2) = 14

Step 2

Convert to Equivalent Fractions with Common Denominator 14

Multiply the numerator and denominator of 5/14 by 1, and multiply the numerator and denominator of 1/2 by 7 so both fractions share the common base 14.

5 × 1/14 × 1 = 5/14 and 1 × 7/2 × 7 = 7/14

Step 3

Add the Numerators

Now add the numerators (5 + 7 = 12) and keep the common denominator 14 unchanged.

5 + 7/14 = 12/14

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 12 and 14, which is 2. Divide both the numerator and denominator by 2.

12 ÷ 2/14 ÷ 2 = 6/7

Step 5
