What is 2/4 plus 10/12? (Answer: 4/3)

Exact Answer

==================================================
Problem: What is 2/4 plus 10/12?
Formula / Expression: 2/4 + 10/12
Final Answer: 1 1/3 (4/3)
==================================================

Step-by-Step Solution:

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

Step 2: Convert to Equivalent Fractions with Common Denominator 12
Multiply the numerator and denominator of 2/4 by 3, and multiply the numerator and denominator of 10/12 by 1 so both fractions share the common base 12.
Working: 2 × 3/4 × 3 = 6/12 and 10 × 1/12 × 1 = 10/12

Step 3: Add the Numerators
Now add the numerators (6 + 10 = 16) and keep the common denominator 12 unchanged.
Working: 6 + 10/12 = 16/12

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 16 and 12, which is 4. Divide both the numerator and denominator by 4.
Working: 16 ÷ 4/12 ÷ 4 = 4/3

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (4) is greater than the denominator (3), divide 4 by 3: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/3.
Working: 4/3 = 1 1/3

Step 6: Decimal & Percentage Representation
Dividing the numerator 4 by denominator 3 produces a repeating decimal (approximately 1.333333, or 133.3333%).
Working: 4 ÷ 3 = 1.333333 (133.3333%)

Key Values:
- Simplified Fraction: 4/3
- Mixed Number Form: 1 1/3
- Decimal Value: 1.333333
- Percentage: 133.3333%

Step-by-Step Solution: 2/4 + 10/12

Step 1

Find the Least Common Denominator (LCD)

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

LCD(4, 12) = 12

Step 2

Convert to Equivalent Fractions with Common Denominator 12

Multiply the numerator and denominator of 2/4 by 3, and multiply the numerator and denominator of 10/12 by 1 so both fractions share the common base 12.

2 × 3/4 × 3 = 6/12 and 10 × 1/12 × 1 = 10/12

Step 3

Add the Numerators

Now add the numerators (6 + 10 = 16) and keep the common denominator 12 unchanged.

6 + 10/12 = 16/12

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 16 and 12, which is 4. Divide both the numerator and denominator by 4.

16 ÷ 4/12 ÷ 4 = 4/3

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (4) is greater than the denominator (3), divide 4 by 3: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/3.

4/3 = 11/3

Step 6

Decimal & Percentage Representation

Dividing the numerator 4 by denominator 3 produces a repeating decimal (approximately 1.333333, or 133.3333%).

4 ÷ 3 = 1.333333 (133.3333%)
