What is 5/7 plus 5/7? (Answer: 10/7)

Exact Answer

==================================================
Problem: What is 5/7 plus 5/7?
Formula / Expression: 5/7 + 5/7
Final Answer: 1 3/7 (10/7)
==================================================

Step-by-Step Solution:

Step 1: Check the Denominators (Like Fractions)
Both fractions already share the identical denominator (7). Because these are like fractions, no conversion to a common denominator is required—we directly add their numerators while keeping the denominator 7.
Working: 5/7 + 5/7

Step 2: Add the Numerators
Now add the numerators (5 + 5 = 10) and keep the common denominator 7 unchanged.
Working: 5 + 5/7 = 10/7

Step 3: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 10 and 7 is 1, confirming that 10/7 cannot be reduced further—it is already in its simplest irreducible form.
Working: 10/7

Step 4: Convert Improper Fraction to a Mixed Number
Since the numerator (10) is greater than the denominator (7), divide 10 by 7: it goes in 1 whole time(s) with a remainder of 3, giving the mixed number 1 3/7.
Working: 10/7 = 1 3/7

Step 5: Decimal & Percentage Representation
Dividing the numerator 10 by denominator 7 produces a repeating decimal (approximately 1.428571, or 142.8571%).
Working: 10 ÷ 7 = 1.428571 (142.8571%)

Key Values:
- Simplified Fraction: 10/7
- Mixed Number Form: 1 3/7
- Decimal Value: 1.428571
- Percentage: 142.8571%
