Answer
$75.3 - 104.645 + 178.96- 47.9$
$= 75.300 - 104.645 + 178.960 - 47.900$
(Converting into like decimals)
$= 75.300 + 178.960 - 104.645 - 47.900$
$= (75.300 + 178.960) - (104.645 + 47.900)$
$= 254.260 - 152.545$
$= 101.715$
Working:
$\ \ \ \ \ 75.300\\ \underline{+178.960}\\ \underline{\ \ \ 254.260}$
$\ 104.645\\ \underline{+47.900}\\ \underline{\ \ 152.545}$
$\ \ \ 254.260\\ \underline{-152.545}\\ \underline{\ \ \ 101.715}$
$= 75.300 - 104.645 + 178.960 - 47.900$
