Exact Answer

==================================================
Problem: What is 2/19 plus 2/10?
Formula / Expression: 2/19 + 2/10
Final Answer: 29/95
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 19 and 10 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 10 = 190.
Working: LCD(19, 10) = 190

Step 2: Convert to Equivalent Fractions with Common Denominator 190
Multiply the numerator and denominator of 2/19 by 10, and multiply the numerator and denominator of 2/10 by 19 so both fractions share the common base 190.
Working: 2 × 10/19 × 10 = 20/190 and 2 × 19/10 × 19 = 38/190

Step 3: Add the Numerators
Now add the numerators (20 + 38 = 58) and keep the common denominator 190 unchanged.
Working: 20 + 38/190 = 58/190

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 58 and 190, which is 2. Divide both the numerator and denominator by 2.
Working: 58 ÷ 2/190 ÷ 2 = 29/95

Step 5: Decimal & Percentage Representation
Dividing the numerator 29 by denominator 95 produces a repeating decimal (approximately 0.305263, or 30.5263%).
Working: 29 ÷ 95 = 0.305263 (30.5263%)

Key Values:
- Simplified Fraction: 29/95
- Mixed Number Form: 29/95
- Decimal Value: 0.305263
- Percentage: 30.5263%

Step-by-Step Solution: 2/19 + 2/10

Step 1

Find the Least Common Denominator (LCD)

The denominators 19 and 10 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 10 = 190.

LCD(19, 10) = 190

Step 2

Convert to Equivalent Fractions with Common Denominator 190

Multiply the numerator and denominator of 2/19 by 10, and multiply the numerator and denominator of 2/10 by 19 so both fractions share the common base 190.

2 × 10/19 × 10 = 20/190 and 2 × 19/10 × 19 = 38/190

Step 3

Add the Numerators

Now add the numerators (20 + 38 = 58) and keep the common denominator 190 unchanged.

20 + 38/190 = 58/190

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 58 and 190, which is 2. Divide both the numerator and denominator by 2.

58 ÷ 2/190 ÷ 2 = 29/95

Step 5

Decimal & Percentage Representation

Dividing the numerator 29 by denominator 95 produces a repeating decimal (approximately 0.305263, or 30.5263%).

29 ÷ 95 = 0.305263 (30.5263%)
