What is 2/22 plus 2/5? (Answer: 27/55)

Exact Answer

==================================================
Problem: What is 2/22 plus 2/5?
Formula / Expression: 2/22 + 2/5
Final Answer: 27/55
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 22 and 5 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 22 × 5 = 110.
Working: LCD(22, 5) = 110

Step 2: Convert to Equivalent Fractions with Common Denominator 110
Multiply the numerator and denominator of 2/22 by 5, and multiply the numerator and denominator of 2/5 by 22 so both fractions share the common base 110.
Working: 2 × 5/22 × 5 = 10/110 and 2 × 22/5 × 22 = 44/110

Step 3: Add the Numerators
Now add the numerators (10 + 44 = 54) and keep the common denominator 110 unchanged.
Working: 10 + 44/110 = 54/110

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 54 and 110, which is 2. Divide both the numerator and denominator by 2.
Working: 54 ÷ 2/110 ÷ 2 = 27/55

Step 5: Decimal & Percentage Representation
Dividing the numerator 27 by denominator 55 produces a repeating decimal (approximately 0.490909, or 49.0909%).
Working: 27 ÷ 55 = 0.490909 (49.0909%)

Key Values:
- Simplified Fraction: 27/55
- Mixed Number Form: 27/55
- Decimal Value: 0.490909
- Percentage: 49.0909%

Step-by-Step Solution: 2/22 + 2/5

Step 1

Find the Least Common Denominator (LCD)

The denominators 22 and 5 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 22 × 5 = 110.

LCD(22, 5) = 110

Step 2

Convert to Equivalent Fractions with Common Denominator 110

Multiply the numerator and denominator of 2/22 by 5, and multiply the numerator and denominator of 2/5 by 22 so both fractions share the common base 110.

2 × 5/22 × 5 = 10/110 and 2 × 22/5 × 22 = 44/110

Step 3

Add the Numerators

Now add the numerators (10 + 44 = 54) and keep the common denominator 110 unchanged.

10 + 44/110 = 54/110

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 54 and 110, which is 2. Divide both the numerator and denominator by 2.

54 ÷ 2/110 ÷ 2 = 27/55

Step 5

Decimal & Percentage Representation

Dividing the numerator 27 by denominator 55 produces a repeating decimal (approximately 0.490909, or 49.0909%).

27 ÷ 55 = 0.490909 (49.0909%)
