What is 155.43 rounded to the nearest whole number ?

155;
rounding to the nearest whole number basically means rounding the decimals so they disappear e.g. 11.5 would round up to 12 because 5+ rounds upwards and below 4 rounds down so say it was 15.34 it would round down so it would be 15.
I hope this helps ;)

Where is your question?
