Write the opposite of each rational number
A)$ 9$
B)$-17.6$

D) $-7 \frac{5}{7 }$
Some one please help! I am not doing very good in Math I'm in grade 9 and I'm struggling I would highly appreciate if someone would help me out. Thanks for taking your time to read this:)
Just change the sign. Remember, if there is no sign shown, it's positive. (I like to say there is an invisible $+$ sign.)
So, if the value is +'ve, it becomes -'ve; and -'ve becomes +'ve.
Note that finding the opposite is the same as multiplying by $-1$.
