1. Quy đồng mẫu số

\(\dfrac{-3}{6}\) và \(\dfrac{7}{4}\) MSC: 12

\(\dfrac{-3}{6}\) = \(\dfrac{-6}{12}\)

\(\dfrac{7}{4}\) = \(\dfrac{21}{12}\)

2. Rút gọn phân số

\(\dfrac{-90}{81}\) = \(\dfrac{-90:9}{81:9}\) = \(\dfrac{-10}{9}\)

3. Tìm n biết 10 ⋮ (n + 1)

⇒ n ∈ { 1; -1; 5; -5; 10; -10}

*n + 1 = 1

n = 1 - 1

n = 0

* n + 1 = -1

n = -1 - 1

n = -2

*n + 1 = 5

n = 5 - 1

n = 5

*n + 1 = -5

n = -5 - 1

n = -6

*n + 1 = 10

n = 10 -1

n = 9

*n + 1 = -10

n = -10 - 1

n = -11

Vậy n ∈ {0; -2; 5; -6; 9; -11}
