Exact Answer

==================================================
Problem: What is 2/40 plus 2/11?
Formula / Expression: 2/40 + 2/11
Final Answer: 51/220
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 40 and 11 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 40 × 11 = 440.
Working: LCD(40, 11) = 440

Step 2: Convert to Equivalent Fractions with Common Denominator 440
Multiply the numerator and denominator of 2/40 by 11, and multiply the numerator and denominator of 2/11 by 40 so both fractions share the common base 440.
Working: 2 × 11/40 × 11 = 22/440 and 2 × 40/11 × 40 = 80/440

Step 3: Add the Numerators
Now add the numerators (22 + 80 = 102) and keep the common denominator 440 unchanged.
Working: 22 + 80/440 = 102/440

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 102 and 440, which is 2. Divide both the numerator and denominator by 2.
Working: 102 ÷ 2/440 ÷ 2 = 51/220

Step 5: Decimal & Percentage Representation
Dividing the numerator 51 by denominator 220 produces a repeating decimal (approximately 0.231818, or 23.1818%).
Working: 51 ÷ 220 = 0.231818 (23.1818%)

Key Values:
- Simplified Fraction: 51/220
- Mixed Number Form: 51/220
- Decimal Value: 0.231818
- Percentage: 23.1818%

Step-by-Step Solution: 2/40 + 2/11

Step 1

Find the Least Common Denominator (LCD)

The denominators 40 and 11 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 40 × 11 = 440.

LCD(40, 11) = 440

Step 2

Convert to Equivalent Fractions with Common Denominator 440

Multiply the numerator and denominator of 2/40 by 11, and multiply the numerator and denominator of 2/11 by 40 so both fractions share the common base 440.

2 × 11/40 × 11 = 22/440 and 2 × 40/11 × 40 = 80/440

Step 3

Add the Numerators

Now add the numerators (22 + 80 = 102) and keep the common denominator 440 unchanged.

22 + 80/440 = 102/440

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 102 and 440, which is 2. Divide both the numerator and denominator by 2.

102 ÷ 2/440 ÷ 2 = 51/220

Step 5

Decimal & Percentage Representation

Dividing the numerator 51 by denominator 220 produces a repeating decimal (approximately 0.231818, or 23.1818%).

51 ÷ 220 = 0.231818 (23.1818%)
