#9 6/9 it’s asking to simplify so you can simplify this by dividing by 3 which is 2/3
#10 7/7 simplify = 1
#11 6/8 simplify by 2 = 3/4
#12 35/50 simplify = 7/10
This is honestly easy math. You simplify just get common demoniaters by multiplying each side to get the same demoniaters, remember whatever you do to the bottom you do to the top.
