I would say either C or D because they give the most information.
Answer: Yes
Step-by-step explanation:
Yes, they are, because if you multiply 2*6=12 and 3*6=18, so here we multiplied both 2 and 3 by the same number (6) and we got the same result 12:18. This method also works with fractions.
Answer:
for 1 I am guessing D and for 2 I am guessing B.
