Exact Answer

==================================================
Problem: What is 2/9 plus 7/16?
Formula / Expression: 2/9 + 7/16
Final Answer: 95/144
==================================================

Step-by-Step Solution:

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

Step 2: Convert to Equivalent Fractions with Common Denominator 144
Multiply the numerator and denominator of 2/9 by 16, and multiply the numerator and denominator of 7/16 by 9 so both fractions share the common base 144.
Working: 2 × 16/9 × 16 = 32/144 and 7 × 9/16 × 9 = 63/144

Step 3: Add the Numerators
Now add the numerators (32 + 63 = 95) and keep the common denominator 144 unchanged.
Working: 32 + 63/144 = 95/144

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 95 and 144 is 1, confirming that 95/144 cannot be reduced further—it is already in its simplest irreducible form.
Working: 95/144

Step 5: Decimal & Percentage Representation
Dividing the numerator 95 by denominator 144 produces a repeating decimal (approximately 0.659722, or 65.9722%).
Working: 95 ÷ 144 = 0.659722 (65.9722%)

Key Values:
- Simplified Fraction: 95/144
- Mixed Number Form: 95/144
- Decimal Value: 0.659722

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

LCD(9, 16) = 144

Step 2

Convert to Equivalent Fractions with Common Denominator 144

Multiply the numerator and denominator of 2/9 by 16, and multiply the numerator and denominator of 7/16 by 9 so both fractions share the common base 144.

2 × 16/9 × 16 = 32/144 and 7 × 9/16 × 9 = 63/144

Step 3

Add the Numerators

Now add the numerators (32 + 63 = 95) and keep the common denominator 144 unchanged.

32 + 63/144 = 95/144

Step 4
