100
Rounded to the nearest whole number, 54.45 is approximately equal to 54.
123.2+54+92.111=269.311 But if this needs to take significant digits into account, then the answer must be rounded to the ones place, (since 54 is the least precise measure given, ending at the ones place) so the answer would be 269.
