Exact Answer

==================================================
Problem: What is 4/44 plus 9/13?
Formula / Expression: 4/44 + 9/13
Final Answer: 112/143
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 44 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 44 × 13 = 572.
Working: LCD(44, 13) = 572

Step 2: Convert to Equivalent Fractions with Common Denominator 572
Multiply the numerator and denominator of 4/44 by 13, and multiply the numerator and denominator of 9/13 by 44 so both fractions share the common base 572.
Working: 4 × 13/44 × 13 = 52/572 and 9 × 44/13 × 44 = 396/572

Step 3: Add the Numerators
Now add the numerators (52 + 396 = 448) and keep the common denominator 572 unchanged.
Working: 52 + 396/572 = 448/572

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 448 and 572, which is 4. Divide both the numerator and denominator by 4.
Working: 448 ÷ 4/572 ÷ 4 = 112/143

Step 5: Decimal & Percentage Representation
Dividing the numerator 112 by denominator 143 produces a repeating decimal (approximately 0.783217, or 78.3217%).
Working: 112 ÷ 143 = 0.783217 (78.3217%)

Key Values:
- Simplified Fraction: 112/143
- Mixed Number Form: 112/143
- Decimal Value: 0.783217
- Percentage: 78.3217%

Step-by-Step Solution: 4/44 + 9/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 44 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 44 × 13 = 572.

LCD(44, 13) = 572

Step 2

Convert to Equivalent Fractions with Common Denominator 572

Multiply the numerator and denominator of 4/44 by 13, and multiply the numerator and denominator of 9/13 by 44 so both fractions share the common base 572.

4 × 13/44 × 13 = 52/572 and 9 × 44/13 × 44 = 396/572

Step 3

Add the Numerators

Now add the numerators (52 + 396 = 448) and keep the common denominator 572 unchanged.

52 + 396/572 = 448/572

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 448 and 572, which is 4. Divide both the numerator and denominator by 4.

448 ÷ 4/572 ÷ 4 = 112/143

Step 5

Decimal & Percentage Representation

Dividing the numerator 112 by denominator 143 produces a repeating decimal (approximately 0.783217, or 78.3217%).

112 ÷ 143 = 0.783217 (78.3217%)
