Choose an appropriate option and fill in the blanks:
900+80+7+2100= 987.2/987.02
Since 900 is in the hundreds place,80 is in the tens place, 7 is in the one's place, and 2100is in the hundredths place
Then the short form of 900+80+7+2100=987.02
Hence, we can write 987.02 in the above blank.
400+5+3100= 405.03/405.3
40+110+2100= 41.2/40.12
100+ 210+3100=107.2370/7
400+40+6+ =446.8810/8100
