Exact Answer

==================================================
Problem: What is 23/50 plus 10/21?
Formula / Expression: 23/50 + 10/21
Final Answer: 983/1050
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 50 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 50 × 21 = 1050.
Working: LCD(50, 21) = 1050

Step 2: Convert to Equivalent Fractions with Common Denominator 1050
Multiply the numerator and denominator of 23/50 by 21, and multiply the numerator and denominator of 10/21 by 50 so both fractions share the common base 1050.
Working: 23 × 21/50 × 21 = 483/1050 and 10 × 50/21 × 50 = 500/1050

Step 3: Add the Numerators
Now add the numerators (483 + 500 = 983) and keep the common denominator 1050 unchanged.
Working: 483 + 500/1050 = 983/1050

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 983 and 1050 is 1, confirming that 983/1050 cannot be reduced further—it is already in its simplest irreducible form.
Working: 983/1050

Step 5: Decimal & Percentage Representation
Dividing the numerator 983 by denominator 1050 produces a repeating decimal (approximately 0.93619, or 93.619%).
Working: 983 ÷ 1050 = 0.93619 (93.619%)

Key Values:
- Simplified Fraction: 983/1050
- Mixed Number Form: 983/1050
- Decimal Value: 0.93619
- Percentage: 93.619%

Step-by-Step Solution: 23/50 + 10/21

Step 1

Find the Least Common Denominator (LCD)

The denominators 50 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 50 × 21 = 1050.

LCD(50, 21) = 1050

Step 2

Convert to Equivalent Fractions with Common Denominator 1050

Multiply the numerator and denominator of 23/50 by 21, and multiply the numerator and denominator of 10/21 by 50 so both fractions share the common base 1050.

23 × 21/50 × 21 = 483/1050 and 10 × 50/21 × 50 = 500/1050

Step 3

Add the Numerators

Now add the numerators (483 + 500 = 983) and keep the common denominator 1050 unchanged.

483 + 500/1050 = 983/1050

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 983 and 1050 is 1, confirming that 983/1050 cannot be reduced further—it is already in its simplest irreducible form.

983/1050

Step 5

Decimal & Percentage Representation

Dividing the numerator 983 by denominator 1050 produces a repeating decimal (approximately 0.93619, or 93.619%).

983 ÷ 1050 = 0.93619 (93.619%)
