What is the whole-number part in the decimal (15.08)?
Answer and explanation
Correct answer: (15)
The whole-number part of a decimal is the part before the decimal point. In 15.08, the decimal point separates 15 from 08. Therefore the whole-number part is 15, making choice A correct. The digits 0 and 8 are after the decimal point and describe the fractional part, which is 0.08 or eight hundredths.
Place value makes the distinction clear: 1 is in the tens place and 5 is in the ones place, so they form the integer 15. The zero in the tenths place and the 8 in the hundredths place together form the decimal portion. Writing 08 alone does not identify the whole-number part, and writing 1508 would remove the decimal point and change the value. Thus 15 is the required answer.
