What is 6/12 plus 2/3? (Answer: 7/6)

Exact Answer

==================================================
Problem: What is 6/12 plus 2/3?
Formula / Expression: 6/12 + 2/3
Final Answer: 1 1/6 (7/6)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 12 is an exact multiple of 3 (3 × 4 = 12). The Least Common Denominator (LCD) is simply 12, meaning we only need to scale one fraction.
Working: LCD(12, 3) = 12

Step 2: Convert to Equivalent Fractions with Common Denominator 12
Multiply the numerator and denominator of 6/12 by 1, and multiply the numerator and denominator of 2/3 by 4 so both fractions share the common base 12.
Working: 6 × 1/12 × 1 = 6/12 and 2 × 4/3 × 4 = 8/12

Step 3: Add the Numerators
Now add the numerators (6 + 8 = 14) and keep the common denominator 12 unchanged.
Working: 6 + 8/12 = 14/12

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

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (7) is greater than the denominator (6), divide 7 by 6: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/6.
Working: 7/6 = 1 1/6

Step 6: Decimal & Percentage Representation
Dividing the numerator 7 by denominator 6 produces a repeating decimal (approximately 1.166667, or 116.6667%).
Working: 7 ÷ 6 = 1.166667 (116.6667%)

Key Values:
- Simplified Fraction: 7/6
- Mixed Number Form: 1 1/6
- Decimal Value: 1.166667
- Percentage: 116.6667%

Step-by-Step Solution: 6/12 + 2/3

Step 1

Find the Least Common Denominator (LCD)

Notice that 12 is an exact multiple of 3 (3 × 4 = 12). The Least Common Denominator (LCD) is simply 12, meaning we only need to scale one fraction.

LCD(12, 3) = 12

Step 2

Convert to Equivalent Fractions with Common Denominator 12

Multiply the numerator and denominator of 6/12 by 1, and multiply the numerator and denominator of 2/3 by 4 so both fractions share the common base 12.

6 × 1/12 × 1 = 6/12 and 2 × 4/3 × 4 = 8/12

Step 3

Add the Numerators

Now add the numerators (6 + 8 = 14) and keep the common denominator 12 unchanged.

6 + 8/12 = 14/12

Step 4

Simplify the Fraction to Lowest Terms

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

14 ÷ 2/12 ÷ 2 = 7/6

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (7) is greater than the denominator (6), divide 7 by 6: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/6.

7/6 = 11/6

Step 6

Decimal & Percentage Representation

Dividing the numerator 7 by denominator 6 produces a repeating decimal (approximately 1.166667, or 116.6667%).

7 ÷ 6 = 1.166667 (116.6667%)
