answer this for me please question in the bottum

OpenStudy (anonymous):

\[-\frac{ 9 }{ 10 }\div \left(-\begin{matrix}4 \\ 5\end{matrix}\right)\]

OpenStudy (anonymous):

you can write this expression differently by multiplying by the reciprocal of the second fraction there the reciprocal of \[-\frac{ 4 }{ 5 } = -\frac{ 5 }{ 4 }\]

OpenStudy (anonymous):

so you just flip the fraction

OpenStudy (anonymous):

and then change the division sign to multiplication: \[-\frac{ 9 }{ 10 } \times -\frac{ 5 }{ 4 }\]

kk

OpenStudy (anonymous):

the double negatives cancel because a negative times a negative is a positive number so: \[\frac{ 9 }{ 10 } \times \frac{ 5 }{ 4 }\]

OpenStudy (anonymous):

and then multiply straight through to get your answer: \[\frac{ 9 \times 5 }{ 10 \times 4 } = \frac{ 45 }{ 40 }\]
