What is 2/10 plus 9/22? (Answer: 67/110)

Exact Answer

==================================================
Problem: What is 2/10 plus 9/22?
Formula / Expression: 2/10 + 9/22
Final Answer: 67/110
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 10 and 22 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 110 (which is smaller than their product 10 × 22 = 220, keeping the calculation simpler).
Working: LCD(10, 22) = 110

Step 2: Convert to Equivalent Fractions with Common Denominator 110
Multiply the numerator and denominator of 2/10 by 11, and multiply the numerator and denominator of 9/22 by 5 so both fractions share the common base 110.
Working: 2 × 11/10 × 11 = 22/110 and 9 × 5/22 × 5 = 45/110

Step 3: Add the Numerators
Now add the numerators (22 + 45 = 67) and keep the common denominator 110 unchanged.
Working: 22 + 45/110 = 67/110

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 67 and 110 is 1, confirming that 67/110 cannot be reduced further—it is already in its simplest irreducible form.
Working: 67/110

Step 5: Decimal & Percentage Representation
Dividing the numerator 67 by denominator 110 produces a repeating decimal (approximately 0.609091, or 60.9091%).
Working: 67 ÷ 110 = 0.609091 (60.9091%)

Key Values:
- Simplified Fraction: 67/110
- Mixed Number Form: 67/110
- Decimal Value: 0.609091
- Percentage: 60.9091%

Step-by-Step Solution: 2/10 + 9/22

Step 1

Find the Least Common Denominator (LCD)

The denominators 10 and 22 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 110 (which is smaller than their product 10 × 22 = 220, keeping the calculation simpler).

LCD(10, 22) = 110

Step 2

Convert to Equivalent Fractions with Common Denominator 110

Multiply the numerator and denominator of 2/10 by 11, and multiply the numerator and denominator of 9/22 by 5 so both fractions share the common base 110.

2 × 11/10 × 11 = 22/110 and 9 × 5/22 × 5 = 45/110

Step 3

Add the Numerators

Now add the numerators (22 + 45 = 67) and keep the common denominator 110 unchanged.

22 + 45/110 = 67/110

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 67 and 110 is 1, confirming that 67/110 cannot be reduced further—it is already in its simplest irreducible form.

67/110

Step 5

Decimal & Percentage Representation

Dividing the numerator 67 by denominator 110 produces a repeating decimal (approximately 0.609091, or 60.9091%).

67 ÷ 110 = 0.609091 (60.9091%)
