Q. Divide. Write your answer in simplest form. n−13n+1÷2
Write Fraction Division: Write the division problem as a fraction.We have the expression (3n+1)/(n−1)÷2. To simplify the division, we can rewrite the division by 2 as multiplication by its reciprocal, which is 1/2.
Reciprocal Multiplication: Rewrite the division as multiplication by the reciprocal.The expression becomes (3n+1)/(n−1)×21.
Multiply Numerators and Denominators: Multiply the numerators and denominators.When multiplying fractions, we multiply the numerators together and the denominators together. So, we have (n−1)×2(3n+1)×1.
Simplify Expression: Simplify the expression.The multiplication of the numerators is straightforward since it's just (3n+1)×1, which is 3n+1. The multiplication of the denominators gives us 2(n−1), which is 2n−2. So, the expression simplifies to 2n−23n+1.
Factor Out Denominator: Factor out the common factor in the denominator, if possible.Looking at the denominator 2n−2, we can factor out a 2, giving us 2(n−1). However, since there is no common factor with the numerator 3n+1, we cannot simplify further.
