What is 4/25 plus 11/13? (Answer: 327/325)

Exact Answer

==================================================
Problem: What is 4/25 plus 11/13?
Formula / Expression: 4/25 + 11/13
Final Answer: 1 2/325 (327/325)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 25 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 25 × 13 = 325.
Working: LCD(25, 13) = 325

Step 2: Convert to Equivalent Fractions with Common Denominator 325
Multiply the numerator and denominator of 4/25 by 13, and multiply the numerator and denominator of 11/13 by 25 so both fractions share the common base 325.
Working: 4 × 13/25 × 13 = 52/325 and 11 × 25/13 × 25 = 275/325

Step 3: Add the Numerators
Now add the numerators (52 + 275 = 327) and keep the common denominator 325 unchanged.
Working: 52 + 275/325 = 327/325

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 327 and 325 is 1, confirming that 327/325 cannot be reduced further—it is already in its simplest irreducible form.
Working: 327/325

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (327) is greater than the denominator (325), divide 327 by 325: it goes in 1 whole time(s) with a remainder of 2, giving the mixed number 1 2/325.
Working: 327/325 = 1 2/325

Step 6: Decimal & Percentage Representation
Dividing the numerator 327 by denominator 325 produces a repeating decimal (approximately 1.006154, or 100.6154%).
Working: 327 ÷ 325 = 1.006154 (100.6154%)

Key Values:
- Simplified Fraction: 327/325
- Mixed Number Form: 1 2/325
- Decimal Value: 1.006154
- Percentage: 100.6154%

Step-by-Step Solution: 4/25 + 11/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 25 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 25 × 13 = 325.

LCD(25, 13) = 325

Step 2

Convert to Equivalent Fractions with Common Denominator 325

Multiply the numerator and denominator of 4/25 by 13, and multiply the numerator and denominator of 11/13 by 25 so both fractions share the common base 325.

4 × 13/25 × 13 = 52/325 and 11 × 25/13 × 25 = 275/325

Step 3

Add the Numerators

Now add the numerators (52 + 275 = 327) and keep the common denominator 325 unchanged.

52 + 275/325 = 327/325

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 327 and 325 is 1, confirming that 327/325 cannot be reduced further—it is already in its simplest irreducible form.

327/325

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (327) is greater than the denominator (325), divide 327 by 325: it goes in 1 whole time(s) with a remainder of 2, giving the mixed number 1 2/325.

327/325 = 12/325

Step 6

Decimal & Percentage Representation

Dividing the numerator 327 by denominator 325 produces a repeating decimal (approximately 1.006154, or 100.6154%).

327 ÷ 325 = 1.006154 (100.6154%)
