Answer:

Hope this helps sorry I'm not really good at explaining math, cause when I do nobody understands.
Here is the work for it I had to do it like this because I don’t have the right tools
Step 1 says to add 7 to both sides
The number 9 would be located between 8 and 10 on a number line. So the answer is C.
3.15 /7 = 0.45
3.20/8 = 0.40
4.10/10 = 0.41
4.80/16 = 0.3
Answer is 1. 7 stamps worth 3.15
No, because unless they have the same number of digits this cannot be done.
Example:
82 and 32 Obviously 82 is greater
But 84 and 324 in this case 324 is greater
