Exact Answer

==================================================
Problem: What is 2/48 plus 6/21?
Formula / Expression: 2/48 + 6/21
Final Answer: 55/168
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 48 and 21 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 336 (which is smaller than their product 48 × 21 = 1008, keeping the calculation simpler).
Working: LCD(48, 21) = 336

Step 2: Convert to Equivalent Fractions with Common Denominator 336
Multiply the numerator and denominator of 2/48 by 7, and multiply the numerator and denominator of 6/21 by 16 so both fractions share the common base 336.
Working: 2 × 7/48 × 7 = 14/336 and 6 × 16/21 × 16 = 96/336

Step 3: Add the Numerators
Now add the numerators (14 + 96 = 110) and keep the common denominator 336 unchanged.
Working: 14 + 96/336 = 110/336

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 110 and 336, which is 2. Divide both the numerator and denominator by 2.
Working: 110 ÷ 2/336 ÷ 2 = 55/168

Step 5: Decimal & Percentage Representation
Dividing the numerator 55 by denominator 168 produces a repeating decimal (approximately 0.327381, or 32.7381%).
Working: 55 ÷ 168 = 0.327381 (32.7381%)

Key Values:
- Simplified Fraction: 55/168
- Mixed Number Form: 55/168
- Decimal Value: 0.327381
- Percentage: 32.7381%

Step-by-Step Solution: 2/48 + 6/21

Step 1

Find the Least Common Denominator (LCD)

The denominators 48 and 21 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 336 (which is smaller than their product 48 × 21 = 1008, keeping the calculation simpler).

LCD(48, 21) = 336

Step 2

Convert to Equivalent Fractions with Common Denominator 336

Multiply the numerator and denominator of 2/48 by 7, and multiply the numerator and denominator of 6/21 by 16 so both fractions share the common base 336.

2 × 7/48 × 7 = 14/336 and 6 × 16/21 × 16 = 96/336

Step 3

Add the Numerators

Now add the numerators (14 + 96 = 110) and keep the common denominator 336 unchanged.

14 + 96/336 = 110/336

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 110 and 336, which is 2. Divide both the numerator and denominator by 2.

110 ÷ 2/336 ÷ 2 = 55/168

Step 5

Decimal & Percentage Representation

Dividing the numerator 55 by denominator 168 produces a repeating decimal (approximately 0.327381, or 32.7381%).

55 ÷ 168 = 0.327381 (32.7381%)
