\(\LARGE\color{black}{ \frac{A}{B}+\left(\begin{matrix} -\frac{C}{D} \\ \end{matrix}\right) ~~~\Longrightarrow ~~~ \frac{A}{B}-\frac{C}{D} }\). appply this to your problem.

Answer 2

okay

Answer 3

what do you get then?

Answer 4

I don't really know what you did, but this is incorrect-:(

Answer 5

\(\Large\color{black}{ \frac{A}{B}+\left(\begin{matrix} -\frac{C}{D} \\ \end{matrix}\right) ~~~\Longrightarrow ~~~ \frac{A}{B}-\frac{C}{D} }\).

Therefore, \(\Large\color{black}{ \frac{5}{18}+\left(\begin{matrix} -\frac{1}{6} \\ \end{matrix}\right) ~~~\Longrightarrow ~~~~~?? }\) . you tell me.

Answer 6

okay, it will become, \(\Large\color{black}{ \frac{5}{18}-\frac{1}{6} }\). Can you subtract the fractions?

Answer 7

(find the common denominator)

Answer 8

it looks like she did (5-1)/(18-6)
which that is not what we are doing here

Answer 9

What did you get?
