What is 2/35 plus 2/10? (Answer: 9/35)

Exact Answer

==================================================
Problem: What is 2/35 plus 2/10?
Formula / Expression: 2/35 + 2/10
Final Answer: 9/35
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 35 and 10 share a common factor (GCD = 5). Finding their Least Common Multiple gives an LCD of 70 (which is smaller than their product 35 × 10 = 350, keeping the calculation simpler).
Working: LCD(35, 10) = 70

Step 2: Convert to Equivalent Fractions with Common Denominator 70
Multiply the numerator and denominator of 2/35 by 2, and multiply the numerator and denominator of 2/10 by 7 so both fractions share the common base 70.
Working: 2 × 2/35 × 2 = 4/70 and 2 × 7/10 × 7 = 14/70

Step 3: Add the Numerators
Now add the numerators (4 + 14 = 18) and keep the common denominator 70 unchanged.
Working: 4 + 14/70 = 18/70

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 18 and 70, which is 2. Divide both the numerator and denominator by 2.
Working: 18 ÷ 2/70 ÷ 2 = 9/35

Step 5: Decimal & Percentage Representation
Dividing the numerator 9 by denominator 35 produces a repeating decimal (approximately 0.257143, or 25.7143%).
Working: 9 ÷ 35 = 0.257143 (25.7143%)

Key Values:
- Simplified Fraction: 9/35
- Mixed Number Form: 9/35
- Decimal Value: 0.257143
- Percentage: 25.7143%
