Exact Answer

==================================================
Problem: What is 3/50 plus 3/13?
Formula / Expression: 3/50 + 3/13
Final Answer: 189/650
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 50 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 50 × 13 = 650.
Working: LCD(50, 13) = 650

Step 2: Convert to Equivalent Fractions with Common Denominator 650
Multiply the numerator and denominator of 3/50 by 13, and multiply the numerator and denominator of 3/13 by 50 so both fractions share the common base 650.
Working: 3 × 13/50 × 13 = 39/650 and 3 × 50/13 × 50 = 150/650

Step 3: Add the Numerators
Now add the numerators (39 + 150 = 189) and keep the common denominator 650 unchanged.
Working: 39 + 150/650 = 189/650

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 189 and 650 is 1, confirming that 189/650 cannot be reduced further—it is already in its simplest irreducible form.
Working: 189/650

Step 5: Decimal & Percentage Representation
Dividing the numerator 189 by denominator 650 produces a repeating decimal (approximately 0.290769, or 29.0769%).
Working: 189 ÷ 650 = 0.290769 (29.0769%)

Key Values:
- Simplified Fraction: 189/650
- Mixed Number Form: 189/650
- Decimal Value: 0.290769

Step-by-Step Solution: 3/50 + 3/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 50 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 50 × 13 = 650.

LCD(50, 13) = 650

Step 2

Convert to Equivalent Fractions with Common Denominator 650

Multiply the numerator and denominator of 3/50 by 13, and multiply the numerator and denominator of 3/13 by 50 so both fractions share the common base 650.

3 × 13/50 × 13 = 39/650 and 3 × 50/13 × 50 = 150/650

Step 3

Add the Numerators

Now add the numerators (39 + 150 = 189) and keep the common denominator 650 unchanged.

39 + 150/650 = 189/650

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 189 and 650 is 1, confirming that 189/650 cannot be reduced further—it is already in its simplest irreducible form.

189/650

Step 5

Decimal & Percentage Representation
