Exact Answer

==================================================
Problem: What is 2/29 plus 2/10?
Formula / Expression: 2/29 + 2/10
Final Answer: 39/145
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 29 and 10 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 29 × 10 = 290.
Working: LCD(29, 10) = 290

Step 2: Convert to Equivalent Fractions with Common Denominator 290
Multiply the numerator and denominator of 2/29 by 10, and multiply the numerator and denominator of 2/10 by 29 so both fractions share the common base 290.
Working: 2 × 10/29 × 10 = 20/290 and 2 × 29/10 × 29 = 58/290

Step 3: Add the Numerators
Now add the numerators (20 + 58 = 78) and keep the common denominator 290 unchanged.
Working: 20 + 58/290 = 78/290

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 78 and 290, which is 2. Divide both the numerator and denominator by 2.
Working: 78 ÷ 2/290 ÷ 2 = 39/145

Step 5: Decimal & Percentage Representation
Dividing the numerator 39 by denominator 145 produces a repeating decimal (approximately 0.268966, or 26.8966%).
Working: 39 ÷ 145 = 0.268966 (26.8966%)

Key Values:
- Simplified Fraction: 39/145
- Mixed Number Form: 39/145
- Decimal Value: 0.268966

Step-by-Step Solution: 2/29 + 2/10

Step 1

Find the Least Common Denominator (LCD)

The denominators 29 and 10 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 29 × 10 = 290.

LCD(29, 10) = 290

Step 2

Convert to Equivalent Fractions with Common Denominator 290

Multiply the numerator and denominator of 2/29 by 10, and multiply the numerator and denominator of 2/10 by 29 so both fractions share the common base 290.

2 × 10/29 × 10 = 20/290 and 2 × 29/10 × 29 = 58/290

Step 3

Add the Numerators

Now add the numerators (20 + 58 = 78) and keep the common denominator 290 unchanged.

20 + 58/290 = 78/290

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 78 and 290, which is 2. Divide both the numerator and denominator by 2.

78 ÷ 2/290 ÷ 2 = 39/145

Step 5

Decimal & Percentage Representation

Dividing the numerator 39 by denominator 145 produces a repeating decimal (approximately 0.268966, or 26.8966%).

39 ÷ 145 = 0.268966 (26.8966%)
