Exact Answer

==================================================
Problem: What is 2/16 plus 4/9?
Formula / Expression: 2/16 + 4/9
Final Answer: 41/72
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 16 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 16 × 9 = 144.
Working: LCD(16, 9) = 144

Step 2: Convert to Equivalent Fractions with Common Denominator 144
Multiply the numerator and denominator of 2/16 by 9, and multiply the numerator and denominator of 4/9 by 16 so both fractions share the common base 144.
Working: 2 × 9/16 × 9 = 18/144 and 4 × 16/9 × 16 = 64/144

Step 3: Add the Numerators
Now add the numerators (18 + 64 = 82) and keep the common denominator 144 unchanged.
Working: 18 + 64/144 = 82/144

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 82 and 144, which is 2. Divide both the numerator and denominator by 2.
Working: 82 ÷ 2/144 ÷ 2 = 41/72

Step 5: Decimal & Percentage Representation
Dividing the numerator 41 by denominator 72 produces a repeating decimal (approximately 0.569444, or 56.9444%).
Working: 41 ÷ 72 = 0.569444 (56.9444%)

Key Values:
- Simplified Fraction: 41/72
- Mixed Number Form: 41/72
- Decimal Value: 0.569444
- Percentage: 56.9444%

Step-by-Step Solution: 2/16 + 4/9

Step 1

Find the Least Common Denominator (LCD)

The denominators 16 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 16 × 9 = 144.

LCD(16, 9) = 144

Step 2

Convert to Equivalent Fractions with Common Denominator 144

Multiply the numerator and denominator of 2/16 by 9, and multiply the numerator and denominator of 4/9 by 16 so both fractions share the common base 144.

2 × 9/16 × 9 = 18/144 and 4 × 16/9 × 16 = 64/144

Step 3

Add the Numerators

Now add the numerators (18 + 64 = 82) and keep the common denominator 144 unchanged.

18 + 64/144 = 82/144

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 82 and 144, which is 2. Divide both the numerator and denominator by 2.

82 ÷ 2/144 ÷ 2 = 41/72

Step 5

Decimal & Percentage Representation

Dividing the numerator 41 by denominator 72 produces a repeating decimal (approximately 0.569444, or 56.9444%).

41 ÷ 72 = 0.569444 (56.9444%)
