Question

answer this for me please question in the bottum

Answer 1

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

Answer 2

you can write this expression differently by multiplying by the reciprocal of the second fraction there

the reciprocal of \[-\frac{ 4 }{ 5 } = -\frac{ 5 }{ 4 }\]

Answer 3

so you just flip the fraction

Answer 4

and then change the division sign to multiplication:

\[-\frac{ 9 }{ 10 } \times -\frac{ 5 }{ 4 }\]

Answer 5

kk

Answer 6

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

Answer 7

and then multiply straight through to get your answer:

\[\frac{ 9 \times 5 }{ 10 \times 4 } = \frac{ 45 }{ 40 }\]
