Exact Answer

==================================================
Problem: What is 9/39 plus 2/4?
Formula / Expression: 9/39 + 2/4
Final Answer: 19/26
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 39 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 39 × 4 = 156.
Working: LCD(39, 4) = 156

Step 2: Convert to Equivalent Fractions with Common Denominator 156
Multiply the numerator and denominator of 9/39 by 4, and multiply the numerator and denominator of 2/4 by 39 so both fractions share the common base 156.
Working: 9 × 4/39 × 4 = 36/156 and 2 × 39/4 × 39 = 78/156

Step 3: Add the Numerators
Now add the numerators (36 + 78 = 114) and keep the common denominator 156 unchanged.
Working: 36 + 78/156 = 114/156

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 114 and 156, which is 6. Divide both the numerator and denominator by 6.
Working: 114 ÷ 6/156 ÷ 6 = 19/26

Step 5: Decimal & Percentage Representation
Dividing the numerator 19 by denominator 26 produces a repeating decimal (approximately 0.730769, or 73.0769%).
Working: 19 ÷ 26 = 0.730769 (73.0769%)

Key Values:
- Simplified Fraction: 19/26
- Mixed Number Form: 19/26
- Decimal Value: 0.730769
- Percentage: 73.0769%

Step-by-Step Solution: 9/39 + 2/4

Step 1

Find the Least Common Denominator (LCD)

The denominators 39 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 39 × 4 = 156.

LCD(39, 4) = 156

Step 2

Convert to Equivalent Fractions with Common Denominator 156

Multiply the numerator and denominator of 9/39 by 4, and multiply the numerator and denominator of 2/4 by 39 so both fractions share the common base 156.

9 × 4/39 × 4 = 36/156 and 2 × 39/4 × 39 = 78/156

Step 3

Add the Numerators

Now add the numerators (36 + 78 = 114) and keep the common denominator 156 unchanged.

36 + 78/156 = 114/156

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 114 and 156, which is 6. Divide both the numerator and denominator by 6.

114 ÷ 6/156 ÷ 6 = 19/26

Step 5

Decimal & Percentage Representation

Dividing the numerator 19 by denominator 26 produces a repeating decimal (approximately 0.730769, or 73.0769%).

19 ÷ 26 = 0.730769 (73.0769%)
