What is 6/24 plus 2/7? (Answer: 15/28)

Exact Answer

==================================================
Problem: What is 6/24 plus 2/7?
Formula / Expression: 6/24 + 2/7
Final Answer: 15/28
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 24 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 24 × 7 = 168.
Working: LCD(24, 7) = 168

Step 2: Convert to Equivalent Fractions with Common Denominator 168
Multiply the numerator and denominator of 6/24 by 7, and multiply the numerator and denominator of 2/7 by 24 so both fractions share the common base 168.
Working: 6 × 7/24 × 7 = 42/168 and 2 × 24/7 × 24 = 48/168

Step 3: Add the Numerators
Now add the numerators (42 + 48 = 90) and keep the common denominator 168 unchanged.
Working: 42 + 48/168 = 90/168

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 90 and 168, which is 6. Divide both the numerator and denominator by 6.
Working: 90 ÷ 6/168 ÷ 6 = 15/28

Step 5: Decimal & Percentage Representation
Dividing the numerator 15 by denominator 28 produces a repeating decimal (approximately 0.535714, or 53.5714%).
Working: 15 ÷ 28 = 0.535714 (53.5714%)

Key Values:
- Simplified Fraction: 15/28
- Mixed Number Form: 15/28
- Decimal Value: 0.535714
- Percentage: 53.5714%

Step-by-Step Solution: 6/24 + 2/7

Step 1

Find the Least Common Denominator (LCD)

The denominators 24 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 24 × 7 = 168.

LCD(24, 7) = 168

Step 2

Convert to Equivalent Fractions with Common Denominator 168

Multiply the numerator and denominator of 6/24 by 7, and multiply the numerator and denominator of 2/7 by 24 so both fractions share the common base 168.

6 × 7/24 × 7 = 42/168 and 2 × 24/7 × 24 = 48/168

Step 3

Add the Numerators

Now add the numerators (42 + 48 = 90) and keep the common denominator 168 unchanged.

42 + 48/168 = 90/168

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 90 and 168, which is 6. Divide both the numerator and denominator by 6.

90 ÷ 6/168 ÷ 6 = 15/28

Step 5

Decimal & Percentage Representation

Dividing the numerator 15 by denominator 28 produces a repeating decimal (approximately 0.535714, or 53.5714%).

15 ÷ 28 = 0.535714 (53.5714%)
