Exact Answer

==================================================
Problem: What is 3/29 plus 3/4?
Formula / Expression: 3/29 + 3/4
Final Answer: 99/116
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 29 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 29 × 4 = 116.
Working: LCD(29, 4) = 116

Step 2: Convert to Equivalent Fractions with Common Denominator 116
Multiply the numerator and denominator of 3/29 by 4, and multiply the numerator and denominator of 3/4 by 29 so both fractions share the common base 116.
Working: 3 × 4/29 × 4 = 12/116 and 3 × 29/4 × 29 = 87/116

Step 3: Add the Numerators
Now add the numerators (12 + 87 = 99) and keep the common denominator 116 unchanged.
Working: 12 + 87/116 = 99/116

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 99 and 116 is 1, confirming that 99/116 cannot be reduced further—it is already in its simplest irreducible form.
Working: 99/116

Step 5: Decimal & Percentage Representation
Dividing the numerator 99 by denominator 116 produces a repeating decimal (approximately 0.853448, or 85.3448%).
Working: 99 ÷ 116 = 0.853448 (85.3448%)

Key Values:
- Simplified Fraction: 99/116
- Mixed Number Form: 99/116
- Decimal Value: 0.853448

Step-by-Step Solution: 3/29 + 3/4

Step 1

Find the Least Common Denominator (LCD)

The denominators 29 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 29 × 4 = 116.

LCD(29, 4) = 116

Step 2

Convert to Equivalent Fractions with Common Denominator 116

Multiply the numerator and denominator of 3/29 by 4, and multiply the numerator and denominator of 3/4 by 29 so both fractions share the common base 116.

3 × 4/29 × 4 = 12/116 and 3 × 29/4 × 29 = 87/116

Step 3

Add the Numerators

Now add the numerators (12 + 87 = 99) and keep the common denominator 116 unchanged.

12 + 87/116 = 99/116

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 99 and 116 is 1, confirming that 99/116 cannot be reduced further—it is already in its simplest irreducible form.
