What is 2/4 plus 8/14? (Answer: 15/14)

Exact Answer

==================================================
Problem: What is 2/4 plus 8/14?
Formula / Expression: 2/4 + 8/14
Final Answer: 1 1/14 (15/14)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 4 and 14 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 28 (which is smaller than their product 4 × 14 = 56, keeping the calculation simpler).
Working: LCD(4, 14) = 28

Step 2: Convert to Equivalent Fractions with Common Denominator 28
Multiply the numerator and denominator of 2/4 by 7, and multiply the numerator and denominator of 8/14 by 2 so both fractions share the common base 28.
Working: 2 × 7/4 × 7 = 14/28 and 8 × 2/14 × 2 = 16/28

Step 3: Add the Numerators
Now add the numerators (14 + 16 = 30) and keep the common denominator 28 unchanged.
Working: 14 + 16/28 = 30/28

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 30 and 28, which is 2. Divide both the numerator and denominator by 2.
Working: 30 ÷ 2/28 ÷ 2 = 15/14

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (15) is greater than the denominator (14), divide 15 by 14: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/14.
Working: 15/14 = 1 1/14

Step 6: Decimal & Percentage Representation
Dividing the numerator 15 by denominator 14 produces a repeating decimal (approximately 1.071429, or 107.1429%).
Working: 15 ÷ 14 = 1.071429 (107.1429%)

Key Values:
- Simplified Fraction: 15/14
- Mixed Number Form: 1 1/14
- Decimal Value: 1.071429
- Percentage: 107.1429%

Step-by-Step Solution: 2/4 + 8/14

Step 1

Find the Least Common Denominator (LCD)

The denominators 4 and 14 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 28 (which is smaller than their product 4 × 14 = 56, keeping the calculation simpler).

LCD(4, 14) = 28

Step 2

Convert to Equivalent Fractions with Common Denominator 28

Multiply the numerator and denominator of 2/4 by 7, and multiply the numerator and denominator of 8/14 by 2 so both fractions share the common base 28.

2 × 7/4 × 7 = 14/28 and 8 × 2/14 × 2 = 16/28

Step 3

Add the Numerators

Now add the numerators (14 + 16 = 30) and keep the common denominator 28 unchanged.

14 + 16/28 = 30/28

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 30 and 28, which is 2. Divide both the numerator and denominator by 2.

30 ÷ 2/28 ÷ 2 = 15/14

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (15) is greater than the denominator (14), divide 15 by 14: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/14.

15/14 = 11/14

Step 6

Decimal & Percentage Representation

Dividing the numerator 15 by denominator 14 produces a repeating decimal (approximately 1.071429, or 107.1429%).

15 ÷ 14 = 1.071429 (107.1429%)
