What is 4/23 plus 3/4? (Answer: 85/92)

Exact Answer

==================================================
Problem: What is 4/23 plus 3/4?
Formula / Expression: 4/23 + 3/4
Final Answer: 85/92
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 23 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 23 × 4 = 92.
Working: LCD(23, 4) = 92

Step 2: Convert to Equivalent Fractions with Common Denominator 92
Multiply the numerator and denominator of 4/23 by 4, and multiply the numerator and denominator of 3/4 by 23 so both fractions share the common base 92.
Working: 4 × 4/23 × 4 = 16/92 and 3 × 23/4 × 23 = 69/92

Step 3: Add the Numerators
Now add the numerators (16 + 69 = 85) and keep the common denominator 92 unchanged.
Working: 16 + 69/92 = 85/92

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 85 and 92 is 1, confirming that 85/92 cannot be reduced further—it is already in its simplest irreducible form.
Working: 85/92

Step 5: Decimal & Percentage Representation
Dividing the numerator 85 by denominator 92 produces a repeating decimal (approximately 0.923913, or 92.3913%).
Working: 85 ÷ 92 = 0.923913 (92.3913%)

Key Values:
- Simplified Fraction: 85/92
- Mixed Number Form: 85/92
- Decimal Value: 0.923913
- Percentage: 92.3913%

Find the Least Common Denominator (LCD)

The denominators 23 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 23 × 4 = 92.

LCD(23, 4) = 92

Step 2

Convert to Equivalent Fractions with Common Denominator 92

Multiply the numerator and denominator of 4/23 by 4, and multiply the numerator and denominator of 3/4 by 23 so both fractions share the common base 92.

4 × 4/23 × 4 = 16/92 and 3 × 23/4 × 23 = 69/92

Step 3

Add the Numerators

Now add the numerators (16 + 69 = 85) and keep the common denominator 92 unchanged.

16 + 69/92 = 85/92

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 85 and 92 is 1, confirming that 85/92 cannot be reduced further—it is already in its simplest irreducible form.
