Exact Answer

==================================================
Problem: What is 2/20 plus 2/17?
Formula / Expression: 2/20 + 2/17
Final Answer: 37/170
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 20 and 17 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 20 × 17 = 340.
Working: LCD(20, 17) = 340

Step 2: Convert to Equivalent Fractions with Common Denominator 340
Multiply the numerator and denominator of 2/20 by 17, and multiply the numerator and denominator of 2/17 by 20 so both fractions share the common base 340.
Working: 2 × 17/20 × 17 = 34/340 and 2 × 20/17 × 20 = 40/340

Step 3: Add the Numerators
Now add the numerators (34 + 40 = 74) and keep the common denominator 340 unchanged.
Working: 34 + 40/340 = 74/340

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 74 and 340, which is 2. Divide both the numerator and denominator by 2.
Working: 74 ÷ 2/340 ÷ 2 = 37/170

Step 5: Decimal & Percentage Representation
Dividing the numerator 37 by denominator 170 produces a repeating decimal (approximately 0.217647, or 21.7647%).
Working: 37 ÷ 170 = 0.217647 (21.7647%)

Key Values:
- Simplified Fraction: 37/170
- Mixed Number Form: 37/170
- Decimal Value: 0.217647

Step-by-Step Solution: 2/20 + 2/17

Step 1

Find the Least Common Denominator (LCD)

The denominators 20 and 17 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 20 × 17 = 340.

LCD(20, 17) = 340

Step 2

Convert to Equivalent Fractions with Common Denominator 340

Multiply the numerator and denominator of 2/20 by 17, and multiply the numerator and denominator of 2/17 by 20 so both fractions share the common base 340.

2 × 17/20 × 17 = 34/340 and 2 × 20/17 × 20 = 40/340

Step 3

Add the Numerators

Now add the numerators (34 + 40 = 74) and keep the common denominator 340 unchanged.

34 + 40/340 = 74/340

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 74 and 340, which is 2. Divide both the numerator and denominator by 2.

74 ÷ 2/340 ÷ 2 = 37/170

Step 5

Decimal & Percentage Representation

Dividing the numerator 37 by denominator 170 produces a repeating decimal (approximately 0.217647, or 21.7647%).

37 ÷ 170 = 0.217647 (21.7647%)
