3. 3.5/9 , 7/18

Answer 1

You might want to rewrite your numbers. hard to tell for me which is ratio and which is division

 

1: 2/3 , 3/9
 
2. 1/2/2/5 , 2/4/2/6
 
3. 3.5/9 , 7/18

Answer 2

JJ,

 

Here's a hint for the first question: If I asked you to reduce 3/9, what would the answer be? Would it equal 1/3? How does that affect your answer?

 

Now, for the second question, what if I asked you to take 1, divide it by 2, divide that number by 2, then divide that number by 5? Would that equal taking 2, dividing it by 4, dividing that number by 2, and then dividing that number by 6?

 

For the final question, consider this line of reasoning. You know 1/2 equals 2/4. But how do you get 2/4 from 1/2? Now what if you applied that same reasoning to determining whether .5/1 equals 1/2? You can apply the same reasoning to your question.
