What is 9/37 plus 2/3? (Answer: 101/111)

Exact Answer

==================================================
Problem: What is 9/37 plus 2/3?
Formula / Expression: 9/37 + 2/3
Final Answer: 101/111
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 37 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 37 × 3 = 111.
Working: LCD(37, 3) = 111

Step 2: Convert to Equivalent Fractions with Common Denominator 111
Multiply the numerator and denominator of 9/37 by 3, and multiply the numerator and denominator of 2/3 by 37 so both fractions share the common base 111.
Working: 9 × 3/37 × 3 = 27/111 and 2 × 37/3 × 37 = 74/111

Step 3: Add the Numerators
Now add the numerators (27 + 74 = 101) and keep the common denominator 111 unchanged.
Working: 27 + 74/111 = 101/111

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 101 and 111 is 1, confirming that 101/111 cannot be reduced further—it is already in its simplest irreducible form.
Working: 101/111

Step 5: Decimal & Percentage Representation
Dividing the numerator 101 by denominator 111 produces a repeating decimal (approximately 0.90991, or 90.991%).
Working: 101 ÷ 111 = 0.90991 (90.991%)

Key Values:
- Simplified Fraction: 101/111
- Mixed Number Form: 101/111
- Decimal Value: 0.90991
- Percentage: 90.991%

Step-by-Step Solution: 9/37 + 2/3

Step 1

Find the Least Common Denominator (LCD)

The denominators 37 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 37 × 3 = 111.

LCD(37, 3) = 111

Step 2

Convert to Equivalent Fractions with Common Denominator 111

Multiply the numerator and denominator of 9/37 by 3, and multiply the numerator and denominator of 2/3 by 37 so both fractions share the common base 111.

9 × 3/37 × 3 = 27/111 and 2 × 37/3 × 37 = 74/111

Step 3

Add the Numerators

Now add the numerators (27 + 74 = 101) and keep the common denominator 111 unchanged.

27 + 74/111 = 101/111

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 101 and 111 is 1, confirming that 101/111 cannot be reduced further—it is already in its simplest irreducible form.

101/111

Step 5
