Question

Find the number in between -8 7/10 and -9 1/5

Answer 1

To find the number we first put them in proper fraction and decimal form:

`-8(7)/(10)=-(87)/(10)=-8.7`
`-9(1)/(5)=-(46)/(5)=-9.2`

Now we know we need and number between -9.2 and -8.7. Doing the same for the options we have:

`\begin{gathered} -9(9)/(10)=-(99)/(10)=-9.9 \\ -9(1)/(10)=-9.1 \\ -8(3)/(10)=-8.3 \\ -8(1)/(10)=-8.1 \end{gathered}`

The number between the options given is -9.1, therefore the answer is B.
