Answer:
#1. 105.5 because of the nine 4 goes to 5
#2. 67,990,000 because of the 4 it doesn't go up
#3. -4.1 because of the 4 the 0 goes to 1
if the number place before the one you are rounding is 5,6,7,8,or 9you go up by one and the rest becomes zeros
if the number place before the one you are rounding is 0,1,2,3,or 4 you stay the same and the rest becomes zeros
 
        
             
        
        
        
<span><span /><span>In Comparing 2 underlined numbers which is 3, we
need to find its place value In order to be able to find the difference of each
given numbers.
First is 6<u>3</u>00 => 6000 + 300 or may also say as 6 thousands + 3
hundreds
therefore the value of underlined number is hundreds
next, 5<u>3</u>0 => 500 + 30 or may also say as 5 hundreds + 3 tens.
Therefore, the value of underlined number tens.
Thus, the difference between the 2 underlined numbers is, the first given digit
falls at hundreds place and the second is in tens place.</span></span>
