What is 9/19 plus 3/4? (Answer: 93/76)

Exact Answer

==================================================
Problem: What is 9/19 plus 3/4?
Formula / Expression: 9/19 + 3/4
Final Answer: 1 17/76 (93/76)
==================================================

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 9/19 by 4, and multiply the numerator and denominator of 3/4 by 19 so both fractions share the common base 76.
Working: 9 × 4/19 × 4 = 36/76 and 3 × 19/4 × 19 = 57/76

Step 3: Add the Numerators
Now add the numerators (36 + 57 = 93) and keep the common denominator 76 unchanged.
Working: 36 + 57/76 = 93/76

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 93 and 76 is 1, confirming that 93/76 cannot be reduced further—it is already in its simplest irreducible form.
Working: 93/76

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (93) is greater than the denominator (76), divide 93 by 76: it goes in 1 whole time(s) with a remainder of 17, giving the mixed number 1 17/76.
Working: 93/76 = 1 17/76

Step 6: Decimal & Percentage Representation
Dividing the numerator 93 by denominator 76 produces a repeating decimal (approximately 1.223684, or 122.3684%).
Working: 93 ÷ 76 = 1.223684 (122.3684%)

Key Values:
- Simplified Fraction: 93/76
- Mixed Number Form: 1 17/76
- Decimal Value: 1.223684
- Percentage: 122.3684%

Step-by-Step Solution: 9/19 + 3/4

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.

LCD(19, 4) = 76

Step 2

Convert to Equivalent Fractions with Common Denominator 76

Multiply the numerator and denominator of 9/19 by 4, and multiply the numerator and denominator of 3/4 by 19 so both fractions share the common base 76.

9 × 4/19 × 4 = 36/76 and 3 × 19/4 × 19 = 57/76

Step 3

Add the Numerators

Now add the numerators (36 + 57 = 93) and keep the common denominator 76 unchanged.

36 + 57/76 = 93/76

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 93 and 76 is 1, confirming that 93/76 cannot be reduced further—it is already in its simplest irreducible form.

93/76

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (93) is greater than the denominator (76), divide 93 by 76: it goes in 1 whole time(s) with a remainder of 17, giving the mixed number 1 17/76.

93/76 = 117/76

Step 6

Decimal & Percentage Representation

Dividing the numerator 93 by denominator 76 produces a repeating decimal (approximately 1.223684, or 122.3684%).

93 ÷ 76 = 1.223684 (122.3684%)
