What is 2/4 plus 9/11? (Answer: 29/22)

Exact Answer

==================================================
Problem: What is 2/4 plus 9/11?
Formula / Expression: 2/4 + 9/11
Final Answer: 1 7/22 (29/22)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 4 and 11 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 4 × 11 = 44.
Working: LCD(4, 11) = 44

Step 2: Convert to Equivalent Fractions with Common Denominator 44
Multiply the numerator and denominator of 2/4 by 11, and multiply the numerator and denominator of 9/11 by 4 so both fractions share the common base 44.
Working: 2 × 11/4 × 11 = 22/44 and 9 × 4/11 × 4 = 36/44

Step 3: Add the Numerators
Now add the numerators (22 + 36 = 58) and keep the common denominator 44 unchanged.
Working: 22 + 36/44 = 58/44

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 58 and 44, which is 2. Divide both the numerator and denominator by 2.
Working: 58 ÷ 2/44 ÷ 2 = 29/22

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (29) is greater than the denominator (22), divide 29 by 22: it goes in 1 whole time(s) with a remainder of 7, giving the mixed number 1 7/22.
Working: 29/22 = 1 7/22

Step 6: Decimal & Percentage Representation
Dividing the numerator 29 by denominator 22 produces a repeating decimal (approximately 1.318182, or 131.8182%).
Working: 29 ÷ 22 = 1.318182 (131.8182%)

Key Values:
- Simplified Fraction: 29/22
- Mixed Number Form: 1 7/22
- Decimal Value: 1.318182
- Percentage: 131.8182%

Step-by-Step Solution: 2/4 + 9/11

Step 1

Find the Least Common Denominator (LCD)

The denominators 4 and 11 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 4 × 11 = 44.

LCD(4, 11) = 44

Step 2

Convert to Equivalent Fractions with Common Denominator 44

Multiply the numerator and denominator of 2/4 by 11, and multiply the numerator and denominator of 9/11 by 4 so both fractions share the common base 44.

2 × 11/4 × 11 = 22/44 and 9 × 4/11 × 4 = 36/44

Step 3

Add the Numerators

Now add the numerators (22 + 36 = 58) and keep the common denominator 44 unchanged.

22 + 36/44 = 58/44

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 58 and 44, which is 2. Divide both the numerator and denominator by 2.

58 ÷ 2/44 ÷ 2 = 29/22

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (29) is greater than the denominator (22), divide 29 by 22: it goes in 1 whole time(s) with a remainder of 7, giving the mixed number 1 7/22.

29/22 = 17/22

Step 6

Decimal & Percentage Representation

Dividing the numerator 29 by denominator 22 produces a repeating decimal (approximately 1.318182, or 131.8182%).

29 ÷ 22 = 1.318182 (131.8182%)
