Exact Answer

==================================================
Problem: What is 7/23 plus 3/9?
Formula / Expression: 7/23 + 3/9
Final Answer: 44/69
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 23 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 23 × 9 = 207.
Working: LCD(23, 9) = 207

Step 2: Convert to Equivalent Fractions with Common Denominator 207
Multiply the numerator and denominator of 7/23 by 9, and multiply the numerator and denominator of 3/9 by 23 so both fractions share the common base 207.
Working: 7 × 9/23 × 9 = 63/207 and 3 × 23/9 × 23 = 69/207

Step 3: Add the Numerators
Now add the numerators (63 + 69 = 132) and keep the common denominator 207 unchanged.
Working: 63 + 69/207 = 132/207

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 132 and 207, which is 3. Divide both the numerator and denominator by 3.
Working: 132 ÷ 3/207 ÷ 3 = 44/69

Step 5: Decimal & Percentage Representation
Dividing the numerator 44 by denominator 69 produces a repeating decimal (approximately 0.637681, or 63.7681%).
Working: 44 ÷ 69 = 0.637681 (63.7681%)

Key Values:
- Simplified Fraction: 44/69
- Mixed Number Form: 44/69
- Decimal Value: 0.637681

Step-by-Step Solution: 7/23 + 3/9

Step 1

Find the Least Common Denominator (LCD)

The denominators 23 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 23 × 9 = 207.

LCD(23, 9) = 207

Step 2

Convert to Equivalent Fractions with Common Denominator 207

Multiply the numerator and denominator of 7/23 by 9, and multiply the numerator and denominator of 3/9 by 23 so both fractions share the common base 207.

7 × 9/23 × 9 = 63/207 and 3 × 23/9 × 23 = 69/207

Step 3

Add the Numerators

Now add the numerators (63 + 69 = 132) and keep the common denominator 207 unchanged.

63 + 69/207 = 132/207

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 132 and 207, which is 3. Divide both the numerator and denominator by 3.

132 ÷ 3/207 ÷ 3 = 44/69

Step 5

Decimal & Percentage Representation

Dividing the numerator 44 by denominator 69 produces a repeating decimal (approximately 0.637681, or 63.7681%).

44 ÷ 69 = 0.637681 (63.7681%)
