What is 2/10 plus 4/6? (Answer: 13/15)

Exact Answer

==================================================
Problem: What is 2/10 plus 4/6?
Formula / Expression: 2/10 + 4/6
Final Answer: 13/15
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 10 and 6 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 30 (which is smaller than their product 10 × 6 = 60, keeping the calculation simpler).
Working: LCD(10, 6) = 30

Step 2: Convert to Equivalent Fractions with Common Denominator 30
Multiply the numerator and denominator of 2/10 by 3, and multiply the numerator and denominator of 4/6 by 5 so both fractions share the common base 30.
Working: 2 × 3/10 × 3 = 6/30 and 4 × 5/6 × 5 = 20/30

Step 3: Add the Numerators
Now add the numerators (6 + 20 = 26) and keep the common denominator 30 unchanged.
Working: 6 + 20/30 = 26/30

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 26 and 30, which is 2. Divide both the numerator and denominator by 2.
Working: 26 ÷ 2/30 ÷ 2 = 13/15

Step 5: Decimal & Percentage Representation
Dividing the numerator 13 by denominator 15 produces a repeating decimal (approximately 0.866667, or 86.6667%).
Working: 13 ÷ 15 = 0.866667 (86.6667%)

Key Values:
- Simplified Fraction: 13/15
- Mixed Number Form: 13/15
- Decimal Value: 0.866667
- Percentage: 86.6667%

The denominators 10 and 6 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 30 (which is smaller than their product 10 × 6 = 60, keeping the calculation simpler).

LCD(10, 6) = 30

Step 2

Convert to Equivalent Fractions with Common Denominator 30

Multiply the numerator and denominator of 2/10 by 3, and multiply the numerator and denominator of 4/6 by 5 so both fractions share the common base 30.

2 × 3/10 × 3 = 6/30 and 4 × 5/6 × 5 = 20/30

Step 3

Add the Numerators

Now add the numerators (6 + 20 = 26) and keep the common denominator 30 unchanged.

6 + 20/30 = 26/30

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 26 and 30, which is 2. Divide both the numerator and denominator by 2.

26 ÷ 2/30 ÷ 2 = 13/15

Step 5

Decimal & Percentage Representation

Dividing the numerator 13 by denominator 15 produces a repeating decimal (approximately 0.866667, or 86.6667%).
