hope that answers your question
For the top part, factors are the numbers that can be multiplied together to get a certain number. So for question 5, what times what is 12? Well 1x12, 2x6, and 3x4. Those numbers are your factors. A tip is that once your lower numbers are start to match your higher, then you get no more. So like once you start saying 3x4=12 you should stop because you can’t go past 3 anymore because of 4.
Now for GCF, that stands for greatest common factor. So for question 9, what are the factors of 40 and 48? List them out then find the Greatest (largest) Common (same) factor. I hope that help!
39 ÷ 28.743 ≈ 1.35
