What is 2/10 plus 9/10? (Answer: 11/10)

Exact Answer

==================================================
Problem: What is 2/10 plus 9/10?
Formula / Expression: 2/10 + 9/10
Final Answer: 1 1/10 (11/10)
==================================================

Step-by-Step Solution:

Step 1: Check the Denominators (Like Fractions)
Both fractions already share the identical denominator (10). Because these are like fractions, no conversion to a common denominator is required—we directly add their numerators while keeping the denominator 10.
Working: 2/10 + 9/10

Step 2: Add the Numerators
Now add the numerators (2 + 9 = 11) and keep the common denominator 10 unchanged.
Working: 2 + 9/10 = 11/10

Step 3: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 11 and 10 is 1, confirming that 11/10 cannot be reduced further—it is already in its simplest irreducible form.
Working: 11/10

Step 4: Convert Improper Fraction to a Mixed Number
Since the numerator (11) is greater than the denominator (10), divide 11 by 10: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/10.
Working: 11/10 = 1 1/10

Step 5: Decimal & Percentage Representation
Dividing the numerator 11 by denominator 10 yields an exact terminating decimal of 1.1 (or 110%).
Working: 11 ÷ 10 = 1.1 (110%)

Key Values:
- Simplified Fraction: 11/10
- Mixed Number Form: 1 1/10
- Decimal Value: 1.1
- Percentage: 110%
