Im a nerd so i know the answer (actually im not a nerd I just stayed in a Holiday express last night)
the answer is 7cd/9-cd/9=6cd/9 PEMDAS 7*cd/9 - cd/9 is the same as 7*2/9-2/9 or 7*2/9- 1*2/9
Im such a nerd

7cd/9-cd/9. you subtract common factors, like cd/9. so subtracting that from both sides, you get 7 - 0, which is obviously 7.

7 is the answer. cd/9 -cd/9 only leaves the 7.

6cd/9 .... obviously cd/9 can be ignored, it's just there to confuse you, look at it as SEVENcd/9 MINUS ONEcd/9
seven minus one
6 ...
and add cd/9 again
so 6cd/9
it's basically in other words, it's 7 of cd/9 minus one of cd/9 .
so 6 cd/9's

2cd/3 iz the correct answer 7cd-1cd is 6...
6 divided by 9 is 2/3
leave your cd since nothing cancelled it
2cd/3 is your correct answer

6cd/9
Pretend the cd/9 =x..
now it becomes 7x-1x
=6x
replace x with cd/9 and you have an answer!
