Step-by-Step Solution: 9/19 + 3/5
Step 1
Find the Least Common Denominator (LCD)
The denominators 19 and 5 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 5 = 95.
LCD(19, 5) = 95
Step 2
Convert to Equivalent Fractions with Common Denominator 95
Multiply the numerator and denominator of 9/19 by 5, and multiply the numerator and denominator of 3/5 by 19 so both fractions share the common base 95.
9 × 5/19 × 5 = 45/95 and 3 × 19/5 × 19 = 57/95
Step 3
Add the Numerators
Now add the numerators (45 + 57 = 102) and keep the common denominator 95 unchanged.
45 + 57/95 = 102/95
Step 4
Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 102 and 95 is 1, confirming that 102/95 cannot be reduced further—it is already in its simplest irreducible form.

Step 5
Convert Improper Fraction to a Mixed Number
Since the numerator (102) is greater than the denominator (95), divide 102 by 95: it goes in 1 whole time(s) with a remainder of 7, giving the mixed number 1 7/95.
102/95 = 17/95
Step 6
Decimal & Percentage Representation
