Exact Answer

==================================================
Problem: What is 6/32 plus 7/21?
Formula / Expression: 6/32 + 7/21
Final Answer: 25/48
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 32 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 32 × 21 = 672.
Working: LCD(32, 21) = 672

Step 2: Convert to Equivalent Fractions with Common Denominator 672
Multiply the numerator and denominator of 6/32 by 21, and multiply the numerator and denominator of 7/21 by 32 so both fractions share the common base 672.
Working: 6 × 21/32 × 21 = 126/672 and 7 × 32/21 × 32 = 224/672

Step 3: Add the Numerators
Now add the numerators (126 + 224 = 350) and keep the common denominator 672 unchanged.
Working: 126 + 224/672 = 350/672

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 350 and 672, which is 14. Divide both the numerator and denominator by 14.
Working: 350 ÷ 14/672 ÷ 14 = 25/48

Step 5: Decimal & Percentage Representation
Dividing the numerator 25 by denominator 48 produces a repeating decimal (approximately 0.520833, or 52.0833%).
Working: 25 ÷ 48 = 0.520833 (52.0833%)

Key Values:
- Simplified Fraction: 25/48
- Mixed Number Form: 25/48
- Decimal Value: 0.520833
- Percentage: 52.0833%

Step-by-Step Solution: 6/32 + 7/21

Step 1

Find the Least Common Denominator (LCD)

The denominators 32 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 32 × 21 = 672.

LCD(32, 21) = 672

Step 2

Convert to Equivalent Fractions with Common Denominator 672

Multiply the numerator and denominator of 6/32 by 21, and multiply the numerator and denominator of 7/21 by 32 so both fractions share the common base 672.

6 × 21/32 × 21 = 126/672 and 7 × 32/21 × 32 = 224/672

Step 3

Add the Numerators

Now add the numerators (126 + 224 = 350) and keep the common denominator 672 unchanged.

126 + 224/672 = 350/672

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 350 and 672, which is 14. Divide both the numerator and denominator by 14.

350 ÷ 14/672 ÷ 14 = 25/48

Step 5

Decimal & Percentage Representation

Dividing the numerator 25 by denominator 48 produces a repeating decimal (approximately 0.520833, or 52.0833%).

25 ÷ 48 = 0.520833 (52.0833%)
