Exact Answer

==================================================
Problem: What is 2/23 plus 2/16?
Formula / Expression: 2/23 + 2/16
Final Answer: 39/184
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 23 and 16 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 23 × 16 = 368.
Working: LCD(23, 16) = 368

Step 2: Convert to Equivalent Fractions with Common Denominator 368
Multiply the numerator and denominator of 2/23 by 16, and multiply the numerator and denominator of 2/16 by 23 so both fractions share the common base 368.
Working: 2 × 16/23 × 16 = 32/368 and 2 × 23/16 × 23 = 46/368

Step 3: Add the Numerators
Now add the numerators (32 + 46 = 78) and keep the common denominator 368 unchanged.
Working: 32 + 46/368 = 78/368

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 78 and 368, which is 2. Divide both the numerator and denominator by 2.
Working: 78 ÷ 2/368 ÷ 2 = 39/184

Step 5: Decimal & Percentage Representation
Dividing the numerator 39 by denominator 184 produces a repeating decimal (approximately 0.211957, or 21.1957%).
Working: 39 ÷ 184 = 0.211957 (21.1957%)

Key Values:
- Simplified Fraction: 39/184
- Mixed Number Form: 39/184
- Decimal Value: 0.211957

Step-by-Step Solution: 2/23 + 2/16

Step 1

Find the Least Common Denominator (LCD)

The denominators 23 and 16 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 23 × 16 = 368.

LCD(23, 16) = 368

Step 2

Convert to Equivalent Fractions with Common Denominator 368

Multiply the numerator and denominator of 2/23 by 16, and multiply the numerator and denominator of 2/16 by 23 so both fractions share the common base 368.

2 × 16/23 × 16 = 32/368 and 2 × 23/16 × 23 = 46/368

Step 3

Add the Numerators

Now add the numerators (32 + 46 = 78) and keep the common denominator 368 unchanged.

32 + 46/368 = 78/368

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 78 and 368, which is 2. Divide both the numerator and denominator by 2.

78 ÷ 2/368 ÷ 2 = 39/184

Step 5

Decimal & Percentage Representation

Dividing the numerator 39 by denominator 184 produces a repeating decimal (approximately 0.211957, or 21.1957%).

39 ÷ 184 = 0.211957 (21.1957%)
