Answers and Step-by-step explanations:
(Important:) Before we solve this equation, it is important to know that the larger the denominator is, the smaller the number's value is (unless it is rounded or simplified and ends up being a greater amount, such as 40/50 = 8/10, which is greater than 3/10). It may be confusing, but I'll explain as we go on.
1.) As I mentioned before, the bigger the denominator; the less it's value. In this situation, 1/4 would be the smallest. The fraction 3/4 is greater than 1/4. But because 7/8 is is greater than 3/4, because 6/8 equals 3/4. The fraction 7/8 is greater than 6/8, therefore making 7/8 being the greatest fraction. So, least to greatest looks like this:
1 3 7
4 4 8
2.) In this problem, 3/10 would be the smallest number given, because 1/2 and 4/5 are greater than this value. For this problem though, it requires several steps. The fraction 4/5 is equal to 8/10, and the fraction 1/2 equals 5/10. And yes, I know that I had mentioned that a larger denominator has less value than a smaller one, but remember what I had also said: that "unless it is rounded or simplified and ends up being a greater amount," then it is more than the smaller denominator. So least to greatest looks like this:
3 1 4
10 2 5

I can answer the rest, but they are very hard to see. Can you please edit your post with a little bit of a better picture of the last two problems so that they are easier for me to see and answer? I would like to help you answer the rest, so if you could do that that would be helpful.
I hope what I wrote so far is helpful, I look forward to your reply.
