Question

Which of the following numbers have a value equal to -5

Answer 1

We must find which of the following numbers has a value equal to -5:

`(-5)/(1),(5)/(1),(10)/(-2),(-5)/(-1),-(5)/(1),-(-5)/(1),-(-5)/(-1),-(-10)/(2).`

To answer this question, we simplify each number:

`\begin{gathered} (-5)/(1)=-5 \\ (5)/(1)=5 \\ (10)/(-2)=(5\cdot2)/(-2)=(5)/(-1)=-5 \\ -(5)/(1)=-5 \\ -(-5)/(1)=-(-5)=5 \\ -(-5)/(-1)=-(5)/(1)=-5 \\ -(-10)/(2)=-(-5\cdot2)/(2)=-(-5)=5 \end{gathered}`

Answer

The numbers that are equal to -5 are:

`\begin{gathered} (-5)/(1) \\ (10)/(-2) \\ -(5)/(1) \\ -(-5)/(-1) \end{gathered}`
