Hey :)
Number 7:
-->Let's find the least common multiple of 4, 10, and 12 by listing again:
4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40... 60
10: 10, 20, 30, 40, 50, 60
12: 12, 24, 36, 48, 60
-->As you can see, the LCM is d or 60
* Just a random thought but did you accidently write 7 for the other one?

Number 8:
-->By factoring the expression, you would be finding a factor that both numbers share (usually the GCF) and divide the whole expression by that number:
"What is the GCF of 54 and 24?"
"6!"
--> So now that you know the GCF or just factor, you can divide the expression by it:
54a+24b
54a(/6)+24b(/6)
9a+4b
--> Sorry if this gets confusing but now you put the end result in parentheses with what you divided it by on the outside
6(9a+4b)
-->Or in other words, answer choice 'c'!

Number 9:
-->Sorry but I can't answer it yet because you didn't say what his recipt is. I can help you once you tell me what's on the receipt :)
