What is 7/34 plus 2/3? (Answer: 89/102)

Exact Answer

==================================================
Problem: What is 7/34 plus 2/3?
Formula / Expression: 7/34 + 2/3
Final Answer: 89/102
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 34 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 34 × 3 = 102.
Working: LCD(34, 3) = 102

Step 2: Convert to Equivalent Fractions with Common Denominator 102
Multiply the numerator and denominator of 7/34 by 3, and multiply the numerator and denominator of 2/3 by 34 so both fractions share the common base 102.
Working: 7 × 3/34 × 3 = 21/102 and 2 × 34/3 × 34 = 68/102

Step 3: Add the Numerators
Now add the numerators (21 + 68 = 89) and keep the common denominator 102 unchanged.
Working: 21 + 68/102 = 89/102

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 89 and 102 is 1, confirming that 89/102 cannot be reduced further—it is already in its simplest irreducible form.
Working: 89/102

Step 5: Decimal & Percentage Representation
Dividing the numerator 89 by denominator 102 produces a repeating decimal (approximately 0.872549, or 87.2549%).
Working: 89 ÷ 102 = 0.872549 (87.2549%)

Key Values:
- Simplified Fraction: 89/102
- Mixed Number Form: 89/102
- Decimal Value: 0.872549
- Percentage: 87.2549%

Step-by-Step Solution: 7/34 + 2/3

Step 1

Find the Least Common Denominator (LCD)

The denominators 34 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 34 × 3 = 102.

LCD(34, 3) = 102

Step 2

Convert to Equivalent Fractions with Common Denominator 102

Multiply the numerator and denominator of 7/34 by 3, and multiply the numerator and denominator of 2/3 by 34 so both fractions share the common base 102.

7 × 3/34 × 3 = 21/102 and 2 × 34/3 × 34 = 68/102

Step 3

Add the Numerators

Now add the numerators (21 + 68 = 89) and keep the common denominator 102 unchanged.

21 + 68/102 = 89/102

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 89 and 102 is 1, confirming that 89/102 cannot be reduced further—it is already in its simplest irreducible form.

89/102

Step 5

Decimal & Percentage Representation
