Q. Divide. Write your answer in simplest form. \newline3n+1n1÷2\frac{3n + 1}{n - 1} \div 2
  1. Write Fraction Division: Write the division problem as a fraction.\newlineWe have the expression (3n+1)/(n1)÷2(3n + 1)/(n - 1) \div 2. To simplify the division, we can rewrite the division by 22 as multiplication by its reciprocal, which is 1/21/2.
  2. Reciprocal Multiplication: Rewrite the division as multiplication by the reciprocal.\newlineThe expression becomes (3n+1)/(n1)×12(3n + 1)/(n - 1) \times \frac{1}{2}.
  3. Multiply Numerators and Denominators: Multiply the numerators and denominators.\newlineWhen multiplying fractions, we multiply the numerators together and the denominators together. So, we have (3n+1)×1(n1)×2\frac{(3n + 1) \times 1}{(n - 1) \times 2}.
  4. Simplify Expression: Simplify the expression.\newlineThe multiplication of the numerators is straightforward since it's just (3n+1)×1(3n + 1) \times 1, which is 3n+13n + 1. The multiplication of the denominators gives us 2(n1)2(n - 1), which is 2n22n - 2. So, the expression simplifies to 3n+12n2\frac{3n + 1}{2n - 2}.
  5. Factor Out Denominator: Factor out the common factor in the denominator, if possible.\newlineLooking at the denominator 2n22n - 2, we can factor out a 22, giving us 2(n1)2(n - 1). However, since there is no common factor with the numerator 3n+13n + 1, we cannot simplify further.
