Step-by-Step Solution: 2/18 + 2/4
Step 1
Find the Least Common Denominator (LCD)
The denominators 18 and 4 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 36 (which is smaller than their product 18 × 4 = 72, keeping the calculation simpler).
LCD(18, 4) = 36
Step 2
Convert to Equivalent Fractions with Common Denominator 36
Multiply the numerator and denominator of 2/18 by 2, and multiply the numerator and denominator of 2/4 by 9 so both fractions share the common base 36.
2 × 2/18 × 2 = 4/36 and 2 × 9/4 × 9 = 18/36
Step 3
Add the Numerators
Now add the numerators (4 + 18 = 22) and keep the common denominator 36 unchanged.
4 + 18/36 = 22/36
Step 4
Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 22 and 36, which is 2. Divide both the numerator and denominator by 2.
22 ÷ 2/36 ÷ 2 = 11/18
Step 5
Decimal & Percentage Representation
Dividing the numerator 11 by denominator 18 produces a repeating decimal (approximately 0.611111, or 61.1111%).
11 ÷ 18 = 0.611111 (61.1111%)
