Exact Answer

==================================================
Problem: What is 3/36 plus 11/13?
Formula / Expression: 3/36 + 11/13
Final Answer: 145/156
==================================================

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 3/36 by 13, and multiply the numerator and denominator of 11/13 by 36 so both fractions share the common base 468.
Working: 3 × 13/36 × 13 = 39/468 and 11 × 36/13 × 36 = 396/468

Step 3: Add the Numerators
Now add the numerators (39 + 396 = 435) and keep the common denominator 468 unchanged.
Working: 39 + 396/468 = 435/468

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 435 and 468, which is 3. Divide both the numerator and denominator by 3.
Working: 435 ÷ 3/468 ÷ 3 = 145/156

Step 5: Decimal & Percentage Representation
Dividing the numerator 145 by denominator 156 produces a repeating decimal (approximately 0.929487, or 92.9487%).
Working: 145 ÷ 156 = 0.929487 (92.9487%)

Key Values:
- Simplified Fraction: 145/156
- Mixed Number Form: 145/156
- Decimal Value: 0.929487
- Percentage: 92.9487%

Step-by-Step Solution: 3/36 + 11/13

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 3/36 by 13, and multiply the numerator and denominator of 11/13 by 36 so both fractions share the common base 468.

3 × 13/36 × 13 = 39/468 and 11 × 36/13 × 36 = 396/468

Step 3

Add the Numerators

Now add the numerators (39 + 396 = 435) and keep the common denominator 468 unchanged.

39 + 396/468 = 435/468

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 435 and 468, which is 3. Divide both the numerator and denominator by 3.

435 ÷ 3/468 ÷ 3 = 145/156

Step 5

Decimal & Percentage Representation

Dividing the numerator 145 by denominator 156 produces a repeating decimal (approximately 0.929487, or 92.9487%).

145 ÷ 156 = 0.929487 (92.9487%)
