What is 4/19 plus 3/4? (Answer: 73/76)

Exact Answer

==================================================
Problem: What is 4/19 plus 3/4?
Formula / Expression: 4/19 + 3/4
Final Answer: 73/76
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 19 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 4 = 76.
Working: LCD(19, 4) = 76

Step 2: Convert to Equivalent Fractions with Common Denominator 76
Multiply the numerator and denominator of 4/19 by 4, and multiply the numerator and denominator of 3/4 by 19 so both fractions share the common base 76.
Working: 4 × 4/19 × 4 = 16/76 and 3 × 19/4 × 19 = 57/76

Step 3: Add the Numerators
Now add the numerators (16 + 57 = 73) and keep the common denominator 76 unchanged.
Working: 16 + 57/76 = 73/76

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 73 and 76 is 1, confirming that 73/76 cannot be reduced further—it is already in its simplest irreducible form.
Working: 73/76

Step 5: Decimal & Percentage Representation
Dividing the numerator 73 by denominator 76 produces a repeating decimal (approximately 0.960526, or 96.0526%).
Working: 73 ÷ 76 = 0.960526 (96.0526%)

Key Values:
- Simplified Fraction: 73/76
- Mixed Number Form: 73/76
- Decimal Value: 0.960526
- Percentage: 96.0526%

Find the Least Common Denominator (LCD)

The denominators 19 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 4 = 76.

LCD(19, 4) = 76

Step 2

Convert to Equivalent Fractions with Common Denominator 76

Multiply the numerator and denominator of 4/19 by 4, and multiply the numerator and denominator of 3/4 by 19 so both fractions share the common base 76.

4 × 4/19 × 4 = 16/76 and 3 × 19/4 × 19 = 57/76

Step 3

Add the Numerators

Now add the numerators (16 + 57 = 73) and keep the common denominator 76 unchanged.

16 + 57/76 = 73/76

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 73 and 76 is 1, confirming that 73/76 cannot be reduced further—it is already in its simplest irreducible form.
