What is 8/35 plus 2/4? (Answer: 51/70)

Exact Answer

==================================================
Problem: What is 8/35 plus 2/4?
Formula / Expression: 8/35 + 2/4
Final Answer: 51/70
==================================================

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 8/35 by 4, and multiply the numerator and denominator of 2/4 by 35 so both fractions share the common base 140.
Working: 8 × 4/35 × 4 = 32/140 and 2 × 35/4 × 35 = 70/140

Step 3: Add the Numerators
Now add the numerators (32 + 70 = 102) and keep the common denominator 140 unchanged.
Working: 32 + 70/140 = 102/140

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 102 and 140, which is 2. Divide both the numerator and denominator by 2.
Working: 102 ÷ 2/140 ÷ 2 = 51/70

Step 5: Decimal & Percentage Representation
Dividing the numerator 51 by denominator 70 produces a repeating decimal (approximately 0.728571, or 72.8571%).
Working: 51 ÷ 70 = 0.728571 (72.8571%)

Key Values:
- Simplified Fraction: 51/70
- Mixed Number Form: 51/70
- Decimal Value: 0.728571
- Percentage: 72.8571%

Step-by-Step Solution: 8/35 + 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 8/35 by 4, and multiply the numerator and denominator of 2/4 by 35 so both fractions share the common base 140.

8 × 4/35 × 4 = 32/140 and 2 × 35/4 × 35 = 70/140

Step 3

Add the Numerators

Now add the numerators (32 + 70 = 102) and keep the common denominator 140 unchanged.

32 + 70/140 = 102/140

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 102 and 140, which is 2. Divide both the numerator and denominator by 2.

102 ÷ 2/140 ÷ 2 = 51/70

Step 5

Decimal & Percentage Representation

Dividing the numerator 51 by denominator 70 produces a repeating decimal (approximately 0.728571, or 72.8571%).

51 ÷ 70 = 0.728571 (72.8571%)
