Okay, so the open sentence is basically telling you that -2 is less than or equal to n+4, and n+4 is less than or equal to seven. Do you know where to go from there?

you would need to make 0.03 a whole number 1st, so you take the decimal point and move it 2 places, and you do that to 8.4.

Now, divide the way you would usually do. If there is a remainder, keep adding 0's until you get the answer with no remainder. If the 0 keeps going on and on just stop after 2 0's.
