What is 9/41 plus 3/4? (Answer: 159/164)

Exact Answer

==================================================
Problem: What is 9/41 plus 3/4?
Formula / Expression: 9/41 + 3/4
Final Answer: 159/164
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 41 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 41 × 4 = 164.
Working: LCD(41, 4) = 164

Step 2: Convert to Equivalent Fractions with Common Denominator 164
Multiply the numerator and denominator of 9/41 by 4, and multiply the numerator and denominator of 3/4 by 41 so both fractions share the common base 164.
Working: 9 × 4/41 × 4 = 36/164 and 3 × 41/4 × 41 = 123/164

Step 3: Add the Numerators
Now add the numerators (36 + 123 = 159) and keep the common denominator 164 unchanged.
Working: 36 + 123/164 = 159/164

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 159 and 164 is 1, confirming that 159/164 cannot be reduced further—it is already in its simplest irreducible form.
Working: 159/164

Step 5: Decimal & Percentage Representation
Dividing the numerator 159 by denominator 164 produces a repeating decimal (approximately 0.969512, or 96.9512%).
Working: 159 ÷ 164 = 0.969512 (96.9512%)

Key Values:
- Simplified Fraction: 159/164
- Mixed Number Form: 159/164
- Decimal Value: 0.969512
- Percentage: 96.9512%

Step-by-Step Solution: 9/41 + 3/4

Step 1

Find the Least Common Denominator (LCD)

The denominators 41 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 41 × 4 = 164.

LCD(41, 4) = 164

Step 2

Convert to Equivalent Fractions with Common Denominator 164

Multiply the numerator and denominator of 9/41 by 4, and multiply the numerator and denominator of 3/4 by 41 so both fractions share the common base 164.

9 × 4/41 × 4 = 36/164 and 3 × 41/4 × 41 = 123/164

Step 3

Add the Numerators

Now add the numerators (36 + 123 = 159) and keep the common denominator 164 unchanged.

36 + 123/164 = 159/164

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 159 and 164 is 1, confirming that 159/164 cannot be reduced further—it is already in its simplest irreducible form.

159/164

Step 5

Decimal & Percentage Representation

Dividing the numerator 159 by denominator 164 produces a repeating decimal (approximately 0.969512, or 96.9512%).

159 ÷ 164 = 0.969512 (96.9512%)
