What is 2/20 plus 3/6? (Answer: 3/5)

Exact Answer

==================================================
Problem: What is 2/20 plus 3/6?
Formula / Expression: 2/20 + 3/6
Final Answer: 3/5
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 20 and 6 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 60 (which is smaller than their product 20 × 6 = 120, keeping the calculation simpler).
Working: LCD(20, 6) = 60

Step 2: Convert to Equivalent Fractions with Common Denominator 60
Multiply the numerator and denominator of 2/20 by 3, and multiply the numerator and denominator of 3/6 by 10 so both fractions share the common base 60.
Working: 2 × 3/20 × 3 = 6/60 and 3 × 10/6 × 10 = 30/60

Step 3: Add the Numerators
Now add the numerators (6 + 30 = 36) and keep the common denominator 60 unchanged.
Working: 6 + 30/60 = 36/60

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 36 and 60, which is 12. Divide both the numerator and denominator by 12.
Working: 36 ÷ 12/60 ÷ 12 = 3/5

Step 5: Decimal & Percentage Representation
Dividing the numerator 3 by denominator 5 yields an exact terminating decimal of 0.6 (or 60%).
Working: 3 ÷ 5 = 0.6 (60%)

Key Values:
- Simplified Fraction: 3/5
- Mixed Number Form: 3/5
- Decimal Value: 0.6
- Percentage: 60%

Step-by-Step Solution: 2/20 + 3/6

Step 1

Find the Least Common Denominator (LCD)

The denominators 20 and 6 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 60 (which is smaller than their product 20 × 6 = 120, keeping the calculation simpler).

LCD(20, 6) = 60

Step 2

Convert to Equivalent Fractions with Common Denominator 60

Multiply the numerator and denominator of 2/20 by 3, and multiply the numerator and denominator of 3/6 by 10 so both fractions share the common base 60.

2 × 3/20 × 3 = 6/60 and 3 × 10/6 × 10 = 30/60

Step 3

Add the Numerators

Now add the numerators (6 + 30 = 36) and keep the common denominator 60 unchanged.

6 + 30/60 = 36/60

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 36 and 60, which is 12. Divide both the numerator and denominator by 12.

36 ÷ 12/60 ÷ 12 = 3/5

Step 5

Decimal & Percentage Representation

Dividing the numerator 3 by denominator 5 yields an exact terminating decimal of 0.6 (or 60%).

3 ÷ 5 = 0.6 (60%)
