What is 8/32 plus 2/7? (Answer: 15/28)

Exact Answer

==================================================
Problem: What is 8/32 plus 2/7?
Formula / Expression: 8/32 + 2/7
Final Answer: 15/28
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 32 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 32 × 7 = 224.
Working: LCD(32, 7) = 224

Step 2: Convert to Equivalent Fractions with Common Denominator 224
Multiply the numerator and denominator of 8/32 by 7, and multiply the numerator and denominator of 2/7 by 32 so both fractions share the common base 224.
Working: 8 × 7/32 × 7 = 56/224 and 2 × 32/7 × 32 = 64/224

Step 3: Add the Numerators
Now add the numerators (56 + 64 = 120) and keep the common denominator 224 unchanged.
Working: 56 + 64/224 = 120/224

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 120 and 224, which is 8. Divide both the numerator and denominator by 8.
Working: 120 ÷ 8/224 ÷ 8 = 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: 8/32 + 2/7

Step 1

Find the Least Common Denominator (LCD)

The denominators 32 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 32 × 7 = 224.

LCD(32, 7) = 224

Step 2

Convert to Equivalent Fractions with Common Denominator 224

Multiply the numerator and denominator of 8/32 by 7, and multiply the numerator and denominator of 2/7 by 32 so both fractions share the common base 224.

8 × 7/32 × 7 = 56/224 and 2 × 32/7 × 32 = 64/224

Step 3

Add the Numerators

Now add the numerators (56 + 64 = 120) and keep the common denominator 224 unchanged.

56 + 64/224 = 120/224

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 120 and 224, which is 8. Divide both the numerator and denominator by 8.

120 ÷ 8/224 ÷ 8 = 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%)
