Exact Answer

==================================================
Problem: What is 2/45 plus 2/22?
Formula / Expression: 2/45 + 2/22
Final Answer: 67/495
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 45 and 22 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 45 × 22 = 990.
Working: LCD(45, 22) = 990

Step 2: Convert to Equivalent Fractions with Common Denominator 990
Multiply the numerator and denominator of 2/45 by 22, and multiply the numerator and denominator of 2/22 by 45 so both fractions share the common base 990.
Working: 2 × 22/45 × 22 = 44/990 and 2 × 45/22 × 45 = 90/990

Step 3: Add the Numerators
Now add the numerators (44 + 90 = 134) and keep the common denominator 990 unchanged.
Working: 44 + 90/990 = 134/990

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 134 and 990, which is 2. Divide both the numerator and denominator by 2.
Working: 134 ÷ 2/990 ÷ 2 = 67/495

Step 5: Decimal & Percentage Representation
Dividing the numerator 67 by denominator 495 produces a repeating decimal (approximately 0.135354, or 13.5354%).
Working: 67 ÷ 495 = 0.135354 (13.5354%)

Key Values:
- Simplified Fraction: 67/495
- Mixed Number Form: 67/495
- Decimal Value: 0.135354

Step-by-Step Solution: 2/45 + 2/22

Step 1

Find the Least Common Denominator (LCD)

The denominators 45 and 22 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 45 × 22 = 990.

LCD(45, 22) = 990

Step 2

Convert to Equivalent Fractions with Common Denominator 990

Multiply the numerator and denominator of 2/45 by 22, and multiply the numerator and denominator of 2/22 by 45 so both fractions share the common base 990.

2 × 22/45 × 22 = 44/990 and 2 × 45/22 × 45 = 90/990

Step 3

Add the Numerators

Now add the numerators (44 + 90 = 134) and keep the common denominator 990 unchanged.

44 + 90/990 = 134/990

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 134 and 990, which is 2. Divide both the numerator and denominator by 2.

134 ÷ 2/990 ÷ 2 = 67/495

Step 5

Decimal & Percentage Representation

Dividing the numerator 67 by denominator 495 produces a repeating decimal (approximately 0.135354, or 13.5354%).

67 ÷ 495 = 0.135354 (13.5354%)
