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\frac{7}{10}=-\frac{87}{10}=-8.7$$-9\frac{1}{5}=-\frac{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:

$\begin{gathered} -9\frac{9}{10}=-\frac{99}{10}=-9.9 \\ -9\frac{1}{10}=-9.1 \\ -8\frac{3}{10}=-8.3 \\ -8\frac{1}{10}=-8.1 \end{gathered}$

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