35/1000 - divide both top and bottom by 5 and you get 7/200, which is in its simplest form
None of the numbers you listed are evenly divisible by 1000.
Yes, 258 is divisible by 6, since 43 x 6 = 258
You could go for the extreme and say that, since both numbers are positive integers, the product is greater than 1. Also, since both numbers are smaller than 1000, the product is less than 1000*1000 = 1000000. You could narrow it down to between 3*500 and 3*600 that is, in the range (1500, 1800). If your mental arithmetic is good, you could do 3*560 and 3*570 = (1680, 1710).
how many times does 258 go into 1000
No, 1000 is a multiple of 10. 10 is a factor of 1000. Factors go into numbers, numbers go into multiples.
-0.258 is equal to -258/1000 so it should be -129/500, if you divide both numbers by 2.

.258 just move the decimal point 3 places to the left.
84 + 86 + 88 = 258
258/1000.........or 129/500
258 ÷ 3 = 86
258 ÷ 3 = 86
