Okay, I can’t really see all of the pictures completely but I’ll try my best to help.
For the page with the equivalent fractions, the answers are:
1/2 = 5/10
3/4 = 9/12
4/10 = 2/5
1/4 = 2/8
I would love to help more but I need more pictures to see the whole problem. I was going to try and help with the sequence problems but I can’t see it.
Anyways, I hope that this helps!

Answer:
2. 33.25
Step-by-step explanation:
In order of operations you start with the part of the equation that is in parentheses. So here you would start with 8.7+4.6. Now whenever there is a number just sitting outside the parentheses, you multiply it by the numbers inside of the parentheses. So in this case, once you've added 8.7 and 4.6, you multiply your answer by 2.5 (which is outside of the parentheses. Here is the solving process:
2.5<u>(8.7+4.6)</u>
<u>2.5(13.3)</u>
33.25
