2. And the difference of \( \frac{3}{3}-\frac{2}{8} \). Begin by finding common multiples of the denominators, \( \frac{3}{4} \) Muttiples of \( 4: 4 \). \( \frac{8}{8} \) Multiples of \( 8: 8 \), What is the least number that can be used as a common denominator?

To find a common denominator for the fractions 3/4 and 2/8, we first look for the least common multiple (LCM) of the denominators 4 and 8. Step 1: List the multiples:  • Multiples of 4: 4, 8, 12, 16, …  • Multiples of 8: 8, 16, 24, … Step 2: Identify the smallest common multiple:  • The smallest number that appears in both lists is 8. Thus, the least number that can be used as a common denominator is 8. Using this common denominator, you could rewrite the fractions as:  • 3/4 = (3 × 2)/(4 × 2) = 6/8  • 2/8 remains 2/8 Then, the difference between the two fractions is:  6/8 − 2/8 = (6 − 2)/8 = 4/8 = 1/2 But to answer the specific question, the least common denominator is 8.
