Exact Answer

==================================================
Problem: What is 2/16 plus 2/9?
Formula / Expression: 2/16 + 2/9
Final Answer: 25/72
==================================================

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 2/9 by 16 so both fractions share the common base 144.
Working: 2 × 9/16 × 9 = 18/144 and 2 × 16/9 × 16 = 32/144

Step 3: Add the Numerators
Now add the numerators (18 + 32 = 50) and keep the common denominator 144 unchanged.
Working: 18 + 32/144 = 50/144

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 50 and 144, which is 2. Divide both the numerator and denominator by 2.
Working: 50 ÷ 2/144 ÷ 2 = 25/72

Step 5: Decimal & Percentage Representation
Dividing the numerator 25 by denominator 72 produces a repeating decimal (approximately 0.347222, or 34.7222%).
Working: 25 ÷ 72 = 0.347222 (34.7222%)

Key Values:
- Simplified Fraction: 25/72
- Mixed Number Form: 25/72
- Decimal Value: 0.347222
- Percentage: 34.7222%

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

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 2/9 by 16 so both fractions share the common base 144.

2 × 9/16 × 9 = 18/144 and 2 × 16/9 × 16 = 32/144

Step 3

Add the Numerators

Now add the numerators (18 + 32 = 50) and keep the common denominator 144 unchanged.

18 + 32/144 = 50/144

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 50 and 144, which is 2. Divide both the numerator and denominator by 2.

50 ÷ 2/144 ÷ 2 = 25/72

Step 5

Decimal & Percentage Representation

Dividing the numerator 25 by denominator 72 produces a repeating decimal (approximately 0.347222, or 34.7222%).

25 ÷ 72 = 0.347222 (34.7222%)
