Exact Answer

==================================================
Problem: What is 2/35 plus 2/12?
Formula / Expression: 2/35 + 2/12
Final Answer: 47/210
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 35 and 12 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 35 × 12 = 420.
Working: LCD(35, 12) = 420

Step 2: Convert to Equivalent Fractions with Common Denominator 420
Multiply the numerator and denominator of 2/35 by 12, and multiply the numerator and denominator of 2/12 by 35 so both fractions share the common base 420.
Working: 2 × 12/35 × 12 = 24/420 and 2 × 35/12 × 35 = 70/420

Step 3: Add the Numerators
Now add the numerators (24 + 70 = 94) and keep the common denominator 420 unchanged.
Working: 24 + 70/420 = 94/420

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 94 and 420, which is 2. Divide both the numerator and denominator by 2.
Working: 94 ÷ 2/420 ÷ 2 = 47/210

Step 5: Decimal & Percentage Representation
Dividing the numerator 47 by denominator 210 produces a repeating decimal (approximately 0.22381, or 22.381%).
Working: 47 ÷ 210 = 0.22381 (22.381%)

Key Values:
- Simplified Fraction: 47/210
- Mixed Number Form: 47/210
- Decimal Value: 0.22381
- Percentage: 22.381%

Step-by-Step Solution: 2/35 + 2/12

Step 1

Find the Least Common Denominator (LCD)

The denominators 35 and 12 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 35 × 12 = 420.

LCD(35, 12) = 420

Step 2

Convert to Equivalent Fractions with Common Denominator 420

Multiply the numerator and denominator of 2/35 by 12, and multiply the numerator and denominator of 2/12 by 35 so both fractions share the common base 420.

2 × 12/35 × 12 = 24/420 and 2 × 35/12 × 35 = 70/420

Step 3

Add the Numerators

Now add the numerators (24 + 70 = 94) and keep the common denominator 420 unchanged.

24 + 70/420 = 94/420

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 94 and 420, which is 2. Divide both the numerator and denominator by 2.

94 ÷ 2/420 ÷ 2 = 47/210

Step 5

Decimal & Percentage Representation

Dividing the numerator 47 by denominator 210 produces a repeating decimal (approximately 0.22381, or 22.381%).

47 ÷ 210 = 0.22381 (22.381%)
