What is 2/7 plus 10/35? (Answer: 4/7)

Exact Answer

==================================================
Problem: What is 2/7 plus 10/35?
Formula / Expression: 2/7 + 10/35
Final Answer: 4/7
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 35 is an exact multiple of 7 (7 × 5 = 35). The Least Common Denominator (LCD) is simply 35, meaning we only need to scale one fraction.
Working: LCD(7, 35) = 35

Step 2: Convert to Equivalent Fractions with Common Denominator 35
Multiply the numerator and denominator of 2/7 by 5, and multiply the numerator and denominator of 10/35 by 1 so both fractions share the common base 35.
Working: 2 × 5/7 × 5 = 10/35 and 10 × 1/35 × 1 = 10/35

Step 3: Add the Numerators
Now add the numerators (10 + 10 = 20) and keep the common denominator 35 unchanged.
Working: 10 + 10/35 = 20/35

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 20 and 35, which is 5. Divide both the numerator and denominator by 5.
Working: 20 ÷ 5/35 ÷ 5 = 4/7

Step 5: Decimal & Percentage Representation
Dividing the numerator 4 by denominator 7 produces a repeating decimal (approximately 0.571429, or 57.1429%).
Working: 4 ÷ 7 = 0.571429 (57.1429%)

Key Values:
- Simplified Fraction: 4/7
- Mixed Number Form: 4/7
- Decimal Value: 0.571429
