Help please At what position on the number line is the red dot located?

it's the 2nd answer thank me later

I can help you, it is B.

I can prove this because there are 5 decimal spots between -1 and -2, so it must go as -2, -1.8 -1.6, -1.4, -1.2 (then -1) if you go down the list, it is the 3rd decimal point down, so it is -1.6.

Hope this helps

27 +27 or 27times 2=54

the diffrence is 0
