Exact Answer

==================================================
Problem: What is 2/35 plus 2/4?
Formula / Expression: 2/35 + 2/4
Final Answer: 39/70
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 35 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 35 × 4 = 140.
Working: LCD(35, 4) = 140

Step 2: Convert to Equivalent Fractions with Common Denominator 140
Multiply the numerator and denominator of 2/35 by 4, and multiply the numerator and denominator of 2/4 by 35 so both fractions share the common base 140.
Working: 2 × 4/35 × 4 = 8/140 and 2 × 35/4 × 35 = 70/140

Step 3: Add the Numerators
Now add the numerators (8 + 70 = 78) and keep the common denominator 140 unchanged.
Working: 8 + 70/140 = 78/140

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 78 and 140, which is 2. Divide both the numerator and denominator by 2.
Working: 78 ÷ 2/140 ÷ 2 = 39/70

Step 5: Decimal & Percentage Representation
Dividing the numerator 39 by denominator 70 produces a repeating decimal (approximately 0.557143, or 55.7143%).
Working: 39 ÷ 70 = 0.557143 (55.7143%)

Key Values:
- Simplified Fraction: 39/70
- Mixed Number Form: 39/70
- Decimal Value: 0.557143
- Percentage: 55.7143%

Step-by-Step Solution: 2/35 + 2/4

Step 1

Find the Least Common Denominator (LCD)

The denominators 35 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 35 × 4 = 140.

LCD(35, 4) = 140

Step 2

Convert to Equivalent Fractions with Common Denominator 140

Multiply the numerator and denominator of 2/35 by 4, and multiply the numerator and denominator of 2/4 by 35 so both fractions share the common base 140.

2 × 4/35 × 4 = 8/140 and 2 × 35/4 × 35 = 70/140

Step 3

Add the Numerators

Now add the numerators (8 + 70 = 78) and keep the common denominator 140 unchanged.

8 + 70/140 = 78/140

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 78 and 140, which is 2. Divide both the numerator and denominator by 2.

78 ÷ 2/140 ÷ 2 = 39/70

Step 5

Decimal & Percentage Representation

Dividing the numerator 39 by denominator 70 produces a repeating decimal (approximately 0.557143, or 55.7143%).

39 ÷ 70 = 0.557143 (55.7143%)
