12.45 rounded to the nearest whole number:
12.45 rounded to the nearest whole number:To round a decimal to the nearest whole number look at the digit in the first decimal place (tenths place). Since the tenths place value is less than 5, then the digit at the ones place remains the same but the digits at the tenths place and thereafter becomes 0.

Since the tenths place value is less than 5, then the digit at the ones place remains the same but the digits at the tenths place and thereafter becomes 0.The digit at the tenths place is 4 and 4 < 5.

Since the tenths place value is less than 5, then the digit at the ones place remains the same but the digits at the tenths place and thereafter becomes 0.The digit at the tenths place is 4 and 4 < 5.The digit at the ones place (2) remains unchanged and the digits to the right of the decimal point means the tenths place and hundredths place becomes 0 (rounded down).
