Question

A rational number P/Q is -ve, If P and Q have signs what r they

Answer 1

They are both negative

Explanation:

`\dashrightarrow \: - ( { \tt{ (P)/(Q)) }}`

• distribute -1 into the bracket:

`\dashrightarrow \: { \tt{ (( - 1 * P) )/(( - 1 * Q)) }} \\ \\ \dashrightarrow \: { \tt{ ( -P)/( -Q ) }}`

Answer 2

`\\ \sf\bull\longmapsto (P)/(Q)`

• Lets convert

`\\ \sf\bull\longmapsto -\left((P)/(Q)\right)`

`\\ \sf\bull\longmapsto (-P)/(-Q)`
