Exact Answer

==================================================
Problem: What is 2/37 plus 4/9?
Formula / Expression: 2/37 + 4/9
Final Answer: 166/333
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 37 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 37 × 9 = 333.
Working: LCD(37, 9) = 333

Step 2: Convert to Equivalent Fractions with Common Denominator 333
Multiply the numerator and denominator of 2/37 by 9, and multiply the numerator and denominator of 4/9 by 37 so both fractions share the common base 333.
Working: 2 × 9/37 × 9 = 18/333 and 4 × 37/9 × 37 = 148/333

Step 3: Add the Numerators
Now add the numerators (18 + 148 = 166) and keep the common denominator 333 unchanged.
Working: 18 + 148/333 = 166/333

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 166 and 333 is 1, confirming that 166/333 cannot be reduced further—it is already in its simplest irreducible form.
Working: 166/333

Step 5: Decimal & Percentage Representation
Dividing the numerator 166 by denominator 333 produces a repeating decimal (approximately 0.498498, or 49.8498%).
Working: 166 ÷ 333 = 0.498498 (49.8498%)

Key Values:
- Simplified Fraction: 166/333
- Mixed Number Form: 166/333
- Decimal Value: 0.498498

Step-by-Step Solution: 2/37 + 4/9

Step 1

Find the Least Common Denominator (LCD)

The denominators 37 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 37 × 9 = 333.

LCD(37, 9) = 333

Step 2

Convert to Equivalent Fractions with Common Denominator 333

Multiply the numerator and denominator of 2/37 by 9, and multiply the numerator and denominator of 4/9 by 37 so both fractions share the common base 333.

2 × 9/37 × 9 = 18/333 and 4 × 37/9 × 37 = 148/333

Step 3

Add the Numerators

Now add the numerators (18 + 148 = 166) and keep the common denominator 333 unchanged.

18 + 148/333 = 166/333

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 166 and 333 is 1, confirming that 166/333 cannot be reduced further—it is already in its simplest irreducible form.
