Question 29664
Answered a few. Sorry I cant read the rest.
The 9th question is wrong. You cannot cancel terms simply because they are common. You have to make sure that these terms are not being added or subtracted to other terms
for e.g 
{{{(2+2+3)/(2+3)}}}
This DOES NOT equal 2
You have to first simplify( Add in this case) before you can cancel them
For the above question the correct answer is {{{7/5}}}
