Exact Answer

==================================================
Problem: What is 17/44 plus 10/21?
Formula / Expression: 17/44 + 10/21
Final Answer: 797/924
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 44 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 44 × 21 = 924.
Working: LCD(44, 21) = 924

Step 2: Convert to Equivalent Fractions with Common Denominator 924
Multiply the numerator and denominator of 17/44 by 21, and multiply the numerator and denominator of 10/21 by 44 so both fractions share the common base 924.
Working: 17 × 21/44 × 21 = 357/924 and 10 × 44/21 × 44 = 440/924

Step 3: Add the Numerators
Now add the numerators (357 + 440 = 797) and keep the common denominator 924 unchanged.
Working: 357 + 440/924 = 797/924

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 797 and 924 is 1, confirming that 797/924 cannot be reduced further—it is already in its simplest irreducible form.
Working: 797/924

Step 5: Decimal & Percentage Representation
Dividing the numerator 797 by denominator 924 produces a repeating decimal (approximately 0.862554, or 86.2554%).
Working: 797 ÷ 924 = 0.862554 (86.2554%)

Key Values:
- Simplified Fraction: 797/924
- Mixed Number Form: 797/924
- Decimal Value: 0.862554

Step-by-Step Solution: 17/44 + 10/21

Step 1

Find the Least Common Denominator (LCD)

The denominators 44 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 44 × 21 = 924.

LCD(44, 21) = 924

Step 2

Convert to Equivalent Fractions with Common Denominator 924

Multiply the numerator and denominator of 17/44 by 21, and multiply the numerator and denominator of 10/21 by 44 so both fractions share the common base 924.

17 × 21/44 × 21 = 357/924 and 10 × 44/21 × 44 = 440/924

Step 3

Add the Numerators

Now add the numerators (357 + 440 = 797) and keep the common denominator 924 unchanged.

357 + 440/924 = 797/924

Step 4

Check if the Fraction Can Be Simplified
