What is 7/34 plus 10/13? (Answer: 431/442)

Exact Answer

==================================================
Problem: What is 7/34 plus 10/13?
Formula / Expression: 7/34 + 10/13
Final Answer: 431/442
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 34 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 34 × 13 = 442.
Working: LCD(34, 13) = 442

Step 2: Convert to Equivalent Fractions with Common Denominator 442
Multiply the numerator and denominator of 7/34 by 13, and multiply the numerator and denominator of 10/13 by 34 so both fractions share the common base 442.
Working: 7 × 13/34 × 13 = 91/442 and 10 × 34/13 × 34 = 340/442

Step 3: Add the Numerators
Now add the numerators (91 + 340 = 431) and keep the common denominator 442 unchanged.
Working: 91 + 340/442 = 431/442

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 431 and 442 is 1, confirming that 431/442 cannot be reduced further—it is already in its simplest irreducible form.
Working: 431/442

Step 5: Decimal & Percentage Representation
Dividing the numerator 431 by denominator 442 produces a repeating decimal (approximately 0.975113, or 97.5113%).
Working: 431 ÷ 442 = 0.975113 (97.5113%)

Key Values:
- Simplified Fraction: 431/442
- Mixed Number Form: 431/442
- Decimal Value: 0.975113
- Percentage: 97.5113%

Step-by-Step Solution: 7/34 + 10/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 34 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 34 × 13 = 442.

LCD(34, 13) = 442

Step 2

Convert to Equivalent Fractions with Common Denominator 442

Multiply the numerator and denominator of 7/34 by 13, and multiply the numerator and denominator of 10/13 by 34 so both fractions share the common base 442.

7 × 13/34 × 13 = 91/442 and 10 × 34/13 × 34 = 340/442

Step 3

Add the Numerators

Now add the numerators (91 + 340 = 431) and keep the common denominator 442 unchanged.

91 + 340/442 = 431/442

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 431 and 442 is 1, confirming that 431/442 cannot be reduced further—it is already in its simplest irreducible form.

431/442

Step 5

Decimal & Percentage Representation

Dividing the numerator 431 by denominator 442 produces a repeating decimal (approximately 0.975113, or 97.5113%).

431 ÷ 442 = 0.975113 (97.5113%)
