What is 4/22 plus 2/5? (Answer: 32/55)

Exact Answer

==================================================
Problem: What is 4/22 plus 2/5?
Formula / Expression: 4/22 + 2/5
Final Answer: 32/55
==================================================

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 4/22 by 5, and multiply the numerator and denominator of 2/5 by 22 so both fractions share the common base 110.
Working: 4 × 5/22 × 5 = 20/110 and 2 × 22/5 × 22 = 44/110

Step 3: Add the Numerators
Now add the numerators (20 + 44 = 64) and keep the common denominator 110 unchanged.
Working: 20 + 44/110 = 64/110

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 64 and 110, which is 2. Divide both the numerator and denominator by 2.
Working: 64 ÷ 2/110 ÷ 2 = 32/55

Step 5: Decimal & Percentage Representation
Dividing the numerator 32 by denominator 55 produces a repeating decimal (approximately 0.581818, or 58.1818%).
Working: 32 ÷ 55 = 0.581818 (58.1818%)

Key Values:
- Simplified Fraction: 32/55
- Mixed Number Form: 32/55
- Decimal Value: 0.581818
- Percentage: 58.1818%

Step-by-Step Solution: 4/22 + 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 4/22 by 5, and multiply the numerator and denominator of 2/5 by 22 so both fractions share the common base 110.

4 × 5/22 × 5 = 20/110 and 2 × 22/5 × 22 = 44/110

Step 3

Add the Numerators

Now add the numerators (20 + 44 = 64) and keep the common denominator 110 unchanged.

20 + 44/110 = 64/110

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 64 and 110, which is 2. Divide both the numerator and denominator by 2.

64 ÷ 2/110 ÷ 2 = 32/55

Step 5

Decimal & Percentage Representation

Dividing the numerator 32 by denominator 55 produces a repeating decimal (approximately 0.581818, or 58.1818%).

32 ÷ 55 = 0.581818 (58.1818%)
