Exact Answer

==================================================
Problem: What is 2/21 plus 6/60?
Formula / Expression: 2/21 + 6/60
Final Answer: 41/210
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 21 and 60 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 420 (which is smaller than their product 21 × 60 = 1260, keeping the calculation simpler).
Working: LCD(21, 60) = 420

Step 2: Convert to Equivalent Fractions with Common Denominator 420
Multiply the numerator and denominator of 2/21 by 20, and multiply the numerator and denominator of 6/60 by 7 so both fractions share the common base 420.
Working: 2 × 20/21 × 20 = 40/420 and 6 × 7/60 × 7 = 42/420

Step 3: Add the Numerators
Now add the numerators (40 + 42 = 82) and keep the common denominator 420 unchanged.
Working: 40 + 42/420 = 82/420

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 82 and 420, which is 2. Divide both the numerator and denominator by 2.
Working: 82 ÷ 2/420 ÷ 2 = 41/210

Step 5: Decimal & Percentage Representation
Dividing the numerator 41 by denominator 210 produces a repeating decimal (approximately 0.195238, or 19.5238%).
Working: 41 ÷ 210 = 0.195238 (19.5238%)

Key Values:
- Simplified Fraction: 41/210
- Mixed Number Form: 41/210
- Decimal Value: 0.195238
- Percentage: 19.5238%

Step-by-Step Solution: 2/21 + 6/60

Step 1

Find the Least Common Denominator (LCD)

The denominators 21 and 60 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 420 (which is smaller than their product 21 × 60 = 1260, keeping the calculation simpler).

LCD(21, 60) = 420

Step 2

Convert to Equivalent Fractions with Common Denominator 420

Multiply the numerator and denominator of 2/21 by 20, and multiply the numerator and denominator of 6/60 by 7 so both fractions share the common base 420.

2 × 20/21 × 20 = 40/420 and 6 × 7/60 × 7 = 42/420

Step 3

Add the Numerators

Now add the numerators (40 + 42 = 82) and keep the common denominator 420 unchanged.

40 + 42/420 = 82/420

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 82 and 420, which is 2. Divide both the numerator and denominator by 2.

82 ÷ 2/420 ÷ 2 = 41/210

Step 5

Decimal & Percentage Representation

Dividing the numerator 41 by denominator 210 produces a repeating decimal (approximately 0.195238, or 19.5238%).

41 ÷ 210 = 0.195238 (19.5238%)
