Exact Answer

==================================================
Problem: What is 4/17 plus 4/7?
Formula / Expression: 4/17 + 4/7
Final Answer: 96/119
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 17 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 17 × 7 = 119.
Working: LCD(17, 7) = 119

Step 2: Convert to Equivalent Fractions with Common Denominator 119
Multiply the numerator and denominator of 4/17 by 7, and multiply the numerator and denominator of 4/7 by 17 so both fractions share the common base 119.
Working: 4 × 7/17 × 7 = 28/119 and 4 × 17/7 × 17 = 68/119

Step 3: Add the Numerators
Now add the numerators (28 + 68 = 96) and keep the common denominator 119 unchanged.
Working: 28 + 68/119 = 96/119

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 96 and 119 is 1, confirming that 96/119 cannot be reduced further—it is already in its simplest irreducible form.
Working: 96/119

Step 5: Decimal & Percentage Representation
Dividing the numerator 96 by denominator 119 produces a repeating decimal (approximately 0.806723, or 80.6723%).
Working: 96 ÷ 119 = 0.806723 (80.6723%)

Key Values:
- Simplified Fraction: 96/119
- Mixed Number Form: 96/119
- Decimal Value: 0.806723

The denominators 17 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 17 × 7 = 119.

LCD(17, 7) = 119

Step 2

Convert to Equivalent Fractions with Common Denominator 119

Multiply the numerator and denominator of 4/17 by 7, and multiply the numerator and denominator of 4/7 by 17 so both fractions share the common base 119.

4 × 7/17 × 7 = 28/119 and 4 × 17/7 × 17 = 68/119

Step 3

Add the Numerators

Now add the numerators (28 + 68 = 96) and keep the common denominator 119 unchanged.

28 + 68/119 = 96/119

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 96 and 119 is 1, confirming that 96/119 cannot be reduced further—it is already in its simplest irreducible form.
