Step-by-Step Solution: 3/4 − 2/3
Step 1
Find the Least Common Denominator (LCD)
The denominators 4 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 4 × 3 = 12.
LCD(4, 3) = 12
Step 2
Convert to Equivalent Fractions with Common Denominator 12
Multiply the numerator and denominator of 3/4 by 3, and multiply the numerator and denominator of 2/3 by 4 so both fractions share the common base 12.
3 × 3/4 × 3 = 9/12 and 2 × 4/3 × 4 = 8/12
Step 3
Subtract the Numerators
Now subtract the numerators (9 − 8 = 1) and keep the common denominator 12 unchanged.
9 − 8/12 = 1/12
Step 4
Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 1 and 12 is 1, confirming that 1/12 cannot be reduced further—it is already in its simplest irreducible form.
1/12
Step 5
Decimal & Percentage Representation
Dividing the numerator 1 by denominator 12 produces a repeating decimal (approximately 0.083333, or 8.3333%).
1 ÷ 12 = 0.083333 (8.3333%)
