Step-by-Step Solution: 3/17 + 2/4
Step 1
Find the Least Common Denominator (LCD)
The denominators 17 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 17 × 4 = 68.
LCD(17, 4) = 68
Step 2
Convert to Equivalent Fractions with Common Denominator 68
Multiply the numerator and denominator of 3/17 by 4, and multiply the numerator and denominator of 2/4 by 17 so both fractions share the common base 68.
3 × 4/17 × 4 = 12/68 and 2 × 17/4 × 17 = 34/68
Step 3
Add the Numerators
Now add the numerators (12 + 34 = 46) and keep the common denominator 68 unchanged.
12 + 34/68 = 46/68
Step 4
Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 46 and 68, which is 2. Divide both the numerator and denominator by 2.
46 ÷ 2/68 ÷ 2 = 23/34
Step 5
Decimal & Percentage Representation
Dividing the numerator 23 by denominator 34 produces a repeating decimal (approximately 0.676471, or 67.6471%).
23 ÷ 34 = 0.676471 (67.6471%)
