Exact Answer

==================================================
Problem: What is 6/48 plus 8/21?
Formula / Expression: 6/48 + 8/21
Final Answer: 85/168
==================================================

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 6/48 by 7, and multiply the numerator and denominator of 8/21 by 16 so both fractions share the common base 336.
Working: 6 × 7/48 × 7 = 42/336 and 8 × 16/21 × 16 = 128/336

Step 3: Add the Numerators
Now add the numerators (42 + 128 = 170) and keep the common denominator 336 unchanged.
Working: 42 + 128/336 = 170/336

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 170 and 336, which is 2. Divide both the numerator and denominator by 2.
Working: 170 ÷ 2/336 ÷ 2 = 85/168

Step 5: Decimal & Percentage Representation
Dividing the numerator 85 by denominator 168 produces a repeating decimal (approximately 0.505952, or 50.5952%).
Working: 85 ÷ 168 = 0.505952 (50.5952%)

Key Values:
- Simplified Fraction: 85/168
- Mixed Number Form: 85/168
- Decimal Value: 0.505952

Step-by-Step Solution: 6/48 + 8/21

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 6/48 by 7, and multiply the numerator and denominator of 8/21 by 16 so both fractions share the common base 336.

6 × 7/48 × 7 = 42/336 and 8 × 16/21 × 16 = 128/336

Step 3

Add the Numerators

Now add the numerators (42 + 128 = 170) and keep the common denominator 336 unchanged.

42 + 128/336 = 170/336

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 170 and 336, which is 2. Divide both the numerator and denominator by 2.

170 ÷ 2/336 ÷ 2 = 85/168

Step 5

Decimal & Percentage Representation

Dividing the numerator 85 by denominator 168 produces a repeating decimal (approximately 0.505952, or 50.5952%).

85 ÷ 168 = 0.505952 (50.5952%)
