Exact Answer

==================================================
Problem: What is 10/36 plus 4/13?
Formula / Expression: 10/36 + 4/13
Final Answer: 137/234
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 36 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 36 × 13 = 468.
Working: LCD(36, 13) = 468

Step 2: Convert to Equivalent Fractions with Common Denominator 468
Multiply the numerator and denominator of 10/36 by 13, and multiply the numerator and denominator of 4/13 by 36 so both fractions share the common base 468.
Working: 10 × 13/36 × 13 = 130/468 and 4 × 36/13 × 36 = 144/468

Step 3: Add the Numerators
Now add the numerators (130 + 144 = 274) and keep the common denominator 468 unchanged.
Working: 130 + 144/468 = 274/468

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 274 and 468, which is 2. Divide both the numerator and denominator by 2.
Working: 274 ÷ 2/468 ÷ 2 = 137/234

Step 5: Decimal & Percentage Representation
Dividing the numerator 137 by denominator 234 produces a repeating decimal (approximately 0.58547, or 58.547%).
Working: 137 ÷ 234 = 0.58547 (58.547%)

Key Values:
- Simplified Fraction: 137/234
- Mixed Number Form: 137/234
- Decimal Value: 0.58547

Step-by-Step Solution: 10/36 + 4/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 36 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 36 × 13 = 468.

LCD(36, 13) = 468

Step 2

Convert to Equivalent Fractions with Common Denominator 468

Multiply the numerator and denominator of 10/36 by 13, and multiply the numerator and denominator of 4/13 by 36 so both fractions share the common base 468.

10 × 13/36 × 13 = 130/468 and 4 × 36/13 × 36 = 144/468

Step 3

Add the Numerators

Now add the numerators (130 + 144 = 274) and keep the common denominator 468 unchanged.

130 + 144/468 = 274/468

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 274 and 468, which is 2. Divide both the numerator and denominator by 2.

274 ÷ 2/468 ÷ 2 = 137/234

Step 5

Decimal & Percentage Representation

Dividing the numerator 137 by denominator 234 produces a repeating decimal (approximately 0.58547, or 58.547%).

137 ÷ 234 = 0.58547 (58.547%)
