Exact Answer

==================================================
Problem: What is 10/50 plus 4/13?
Formula / Expression: 10/50 + 4/13
Final Answer: 33/65
==================================================

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 10/50 by 13, and multiply the numerator and denominator of 4/13 by 50 so both fractions share the common base 650.
Working: 10 × 13/50 × 13 = 130/650 and 4 × 50/13 × 50 = 200/650

Step 3: Add the Numerators
Now add the numerators (130 + 200 = 330) and keep the common denominator 650 unchanged.
Working: 130 + 200/650 = 330/650

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 330 and 650, which is 10. Divide both the numerator and denominator by 10.
Working: 330 ÷ 10/650 ÷ 10 = 33/65

Step 5: Decimal & Percentage Representation
Dividing the numerator 33 by denominator 65 produces a repeating decimal (approximately 0.507692, or 50.7692%).
Working: 33 ÷ 65 = 0.507692 (50.7692%)

Key Values:
- Simplified Fraction: 33/65
- Mixed Number Form: 33/65
- Decimal Value: 0.507692
- Percentage: 50.7692%

Step-by-Step Solution: 10/50 + 4/13

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 10/50 by 13, and multiply the numerator and denominator of 4/13 by 50 so both fractions share the common base 650.

10 × 13/50 × 13 = 130/650 and 4 × 50/13 × 50 = 200/650

Step 3

Add the Numerators

Now add the numerators (130 + 200 = 330) and keep the common denominator 650 unchanged.

130 + 200/650 = 330/650

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 330 and 650, which is 10. Divide both the numerator and denominator by 10.

330 ÷ 10/650 ÷ 10 = 33/65

Step 5

Decimal & Percentage Representation

Dividing the numerator 33 by denominator 65 produces a repeating decimal (approximately 0.507692, or 50.7692%).

33 ÷ 65 = 0.507692 (50.7692%)
