What is 2/8 plus 8/14? (Answer: 23/28)

Exact Answer

==================================================
Problem: What is 2/8 plus 8/14?
Formula / Expression: 2/8 + 8/14
Final Answer: 23/28
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 8 and 14 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 56 (which is smaller than their product 8 × 14 = 112, keeping the calculation simpler).
Working: LCD(8, 14) = 56

Step 2: Convert to Equivalent Fractions with Common Denominator 56
Multiply the numerator and denominator of 2/8 by 7, and multiply the numerator and denominator of 8/14 by 4 so both fractions share the common base 56.
Working: 2 × 7/8 × 7 = 14/56 and 8 × 4/14 × 4 = 32/56

Step 3: Add the Numerators
Now add the numerators (14 + 32 = 46) and keep the common denominator 56 unchanged.
Working: 14 + 32/56 = 46/56

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 46 and 56, which is 2. Divide both the numerator and denominator by 2.
Working: 46 ÷ 2/56 ÷ 2 = 23/28

Step 5: Decimal & Percentage Representation
Dividing the numerator 23 by denominator 28 produces a repeating decimal (approximately 0.821429, or 82.1429%).
Working: 23 ÷ 28 = 0.821429 (82.1429%)

Key Values:
- Simplified Fraction: 23/28
- Mixed Number Form: 23/28
- Decimal Value: 0.821429

The denominators 8 and 14 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 56 (which is smaller than their product 8 × 14 = 112, keeping the calculation simpler).

LCD(8, 14) = 56

Step 2

Convert to Equivalent Fractions with Common Denominator 56

Multiply the numerator and denominator of 2/8 by 7, and multiply the numerator and denominator of 8/14 by 4 so both fractions share the common base 56.

2 × 7/8 × 7 = 14/56 and 8 × 4/14 × 4 = 32/56

Step 3

Add the Numerators

Now add the numerators (14 + 32 = 46) and keep the common denominator 56 unchanged.

14 + 32/56 = 46/56

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 46 and 56, which is 2. Divide both the numerator and denominator by 2.

46 ÷ 2/56 ÷ 2 = 23/28

Step 5

Decimal & Percentage Representation

Dividing the numerator 23 by denominator 28 produces a repeating decimal (approximately 0.821429, or 82.1429%).
