What is 17/32 plus 7/13? (Answer: 445/416)

Exact Answer

==================================================
Problem: What is 17/32 plus 7/13?
Formula / Expression: 17/32 + 7/13
Final Answer: 1 29/416 (445/416)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 32 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 32 × 13 = 416.
Working: LCD(32, 13) = 416

Step 2: Convert to Equivalent Fractions with Common Denominator 416
Multiply the numerator and denominator of 17/32 by 13, and multiply the numerator and denominator of 7/13 by 32 so both fractions share the common base 416.
Working: 17 × 13/32 × 13 = 221/416 and 7 × 32/13 × 32 = 224/416

Step 3: Add the Numerators
Now add the numerators (221 + 224 = 445) and keep the common denominator 416 unchanged.
Working: 221 + 224/416 = 445/416

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 445 and 416 is 1, confirming that 445/416 cannot be reduced further—it is already in its simplest irreducible form.
Working: 445/416

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (445) is greater than the denominator (416), divide 445 by 416: it goes in 1 whole time(s) with a remainder of 29, giving the mixed number 1 29/416.
Working: 445/416 = 1 29/416

Step 6: Decimal & Percentage Representation
Dividing the numerator 445 by denominator 416 produces a repeating decimal (approximately 1.069712, or 106.9712%).
Working: 445 ÷ 416 = 1.069712 (106.9712%)

Key Values:
- Simplified Fraction: 445/416
- Mixed Number Form: 1 29/416
- Decimal Value: 1.069712
- Percentage: 106.9712%

Step-by-Step Solution: 17/32 + 7/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 32 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 32 × 13 = 416.

LCD(32, 13) = 416

Step 2

Convert to Equivalent Fractions with Common Denominator 416

Multiply the numerator and denominator of 17/32 by 13, and multiply the numerator and denominator of 7/13 by 32 so both fractions share the common base 416.

17 × 13/32 × 13 = 221/416 and 7 × 32/13 × 32 = 224/416

Step 3

Add the Numerators

Now add the numerators (221 + 224 = 445) and keep the common denominator 416 unchanged.

221 + 224/416 = 445/416

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 445 and 416 is 1, confirming that 445/416 cannot be reduced further—it is already in its simplest irreducible form.

445/416

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (445) is greater than the denominator (416), divide 445 by 416: it goes in 1 whole time(s) with a remainder of 29, giving the mixed number 1 29/416.

445/416 = 129/416

Step 6

Decimal & Percentage Representation

Dividing the numerator 445 by denominator 416 produces a repeating decimal (approximately 1.069712, or 106.9712%).

445 ÷ 416 = 1.069712 (106.9712%)
