What is 2/23 plus 2/7? (Answer: 60/161)

Exact Answer

==================================================
Problem: What is 2/23 plus 2/7?
Formula / Expression: 2/23 + 2/7
Final Answer: 60/161
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 23 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 23 × 7 = 161.
Working: LCD(23, 7) = 161

Step 2: Convert to Equivalent Fractions with Common Denominator 161
Multiply the numerator and denominator of 2/23 by 7, and multiply the numerator and denominator of 2/7 by 23 so both fractions share the common base 161.
Working: 2 × 7/23 × 7 = 14/161 and 2 × 23/7 × 23 = 46/161

Step 3: Add the Numerators
Now add the numerators (14 + 46 = 60) and keep the common denominator 161 unchanged.
Working: 14 + 46/161 = 60/161

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 60 and 161 is 1, confirming that 60/161 cannot be reduced further—it is already in its simplest irreducible form.
Working: 60/161

Step 5: Decimal & Percentage Representation
Dividing the numerator 60 by denominator 161 produces a repeating decimal (approximately 0.372671, or 37.2671%).
Working: 60 ÷ 161 = 0.372671 (37.2671%)

Key Values:
- Simplified Fraction: 60/161
- Mixed Number Form: 60/161
- Decimal Value: 0.372671

Step-by-Step Solution: 2/23 + 2/7

Step 1

Find the Least Common Denominator (LCD)

The denominators 23 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 23 × 7 = 161.

LCD(23, 7) = 161

Step 2

Convert to Equivalent Fractions with Common Denominator 161

Multiply the numerator and denominator of 2/23 by 7, and multiply the numerator and denominator of 2/7 by 23 so both fractions share the common base 161.

2 × 7/23 × 7 = 14/161 and 2 × 23/7 × 23 = 46/161

Step 3

Add the Numerators

Now add the numerators (14 + 46 = 60) and keep the common denominator 161 unchanged.

14 + 46/161 = 60/161

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 60 and 161 is 1, confirming that 60/161 cannot be reduced further—it is already in its simplest irreducible form.

60/161

Step 5

Decimal & Percentage Representation

Dividing the numerator 60 by denominator 161 produces a repeating decimal (approximately 0.372671, or 37.2671%).
