The choose C. –2/15
(-2/15) +(-13/5) =(-13/5) +a/b
a/b = (-2/15)+(-13/5) - (-13/5)
a/b = (-2/15) - ( 39/15) +(39/15)
a/b = –2/15
I hope I helped you ^_^

hope it helps you❤
10-25x=5
subtract 10 from both sides so 5-10 is -5
so now your left with -25x=-5 then divdie -25x by -5 and rememeber -5 divided by a negative is a positive and positive divided by a posivte is a positive and negavite divided by a positive is negavtive or positive divided by a negative is a negative
so when you divide -25x by -5 you get 5 so your answer is x=-5
Think about it like 3 is out of 100. Your answer is 3.
