What is 4/33 plus 2/7? (Answer: 94/231)

Exact Answer

==================================================
Problem: What is 4/33 plus 2/7?
Formula / Expression: 4/33 + 2/7
Final Answer: 94/231
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 33 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 33 × 7 = 231.
Working: LCD(33, 7) = 231

Step 2: Convert to Equivalent Fractions with Common Denominator 231
Multiply the numerator and denominator of 4/33 by 7, and multiply the numerator and denominator of 2/7 by 33 so both fractions share the common base 231.
Working: 4 × 7/33 × 7 = 28/231 and 2 × 33/7 × 33 = 66/231

Step 3: Add the Numerators
Now add the numerators (28 + 66 = 94) and keep the common denominator 231 unchanged.
Working: 28 + 66/231 = 94/231

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 94 and 231 is 1, confirming that 94/231 cannot be reduced further—it is already in its simplest irreducible form.
Working: 94/231

Step 5: Decimal & Percentage Representation
Dividing the numerator 94 by denominator 231 produces a repeating decimal (approximately 0.406926, or 40.6926%).
Working: 94 ÷ 231 = 0.406926 (40.6926%)

Key Values:
- Simplified Fraction: 94/231
- Mixed Number Form: 94/231
- Decimal Value: 0.406926
- Percentage: 40.6926%

Step-by-Step Solution: 4/33 + 2/7

Step 1

Find the Least Common Denominator (LCD)

The denominators 33 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 33 × 7 = 231.

LCD(33, 7) = 231

Step 2

Convert to Equivalent Fractions with Common Denominator 231

Multiply the numerator and denominator of 4/33 by 7, and multiply the numerator and denominator of 2/7 by 33 so both fractions share the common base 231.

4 × 7/33 × 7 = 28/231 and 2 × 33/7 × 33 = 66/231

Step 3

Add the Numerators

Now add the numerators (28 + 66 = 94) and keep the common denominator 231 unchanged.

28 + 66/231 = 94/231

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 94 and 231 is 1, confirming that 94/231 cannot be reduced further—it is already in its simplest irreducible form.

94/231

Step 5

Decimal & Percentage Representation
