Exact Answer

==================================================
Problem: What is 2/30 plus 2/23?
Formula / Expression: 2/30 + 2/23
Final Answer: 53/345
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 30 and 23 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 30 × 23 = 690.
Working: LCD(30, 23) = 690

Step 2: Convert to Equivalent Fractions with Common Denominator 690
Multiply the numerator and denominator of 2/30 by 23, and multiply the numerator and denominator of 2/23 by 30 so both fractions share the common base 690.
Working: 2 × 23/30 × 23 = 46/690 and 2 × 30/23 × 30 = 60/690

Step 3: Add the Numerators
Now add the numerators (46 + 60 = 106) and keep the common denominator 690 unchanged.
Working: 46 + 60/690 = 106/690

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 106 and 690, which is 2. Divide both the numerator and denominator by 2.
Working: 106 ÷ 2/690 ÷ 2 = 53/345

Step 5: Decimal & Percentage Representation
Dividing the numerator 53 by denominator 345 produces a repeating decimal (approximately 0.153623, or 15.3623%).
Working: 53 ÷ 345 = 0.153623 (15.3623%)

Key Values:
- Simplified Fraction: 53/345
- Mixed Number Form: 53/345
- Decimal Value: 0.153623
- Percentage: 15.3623%

Step-by-Step Solution: 2/30 + 2/23

Step 1

Find the Least Common Denominator (LCD)

The denominators 30 and 23 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 30 × 23 = 690.

LCD(30, 23) = 690

Step 2

Convert to Equivalent Fractions with Common Denominator 690

Multiply the numerator and denominator of 2/30 by 23, and multiply the numerator and denominator of 2/23 by 30 so both fractions share the common base 690.

2 × 23/30 × 23 = 46/690 and 2 × 30/23 × 30 = 60/690

Step 3

Add the Numerators

Now add the numerators (46 + 60 = 106) and keep the common denominator 690 unchanged.

46 + 60/690 = 106/690

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 106 and 690, which is 2. Divide both the numerator and denominator by 2.

106 ÷ 2/690 ÷ 2 = 53/345

Step 5

Decimal & Percentage Representation

Dividing the numerator 53 by denominator 345 produces a repeating decimal (approximately 0.153623, or 15.3623%).

53 ÷ 345 = 0.153623 (15.3623%)
