|
Answer» No because whole number is started from zero and integer are -2 -1 0 +1 +2 +3 etc Never No , it is false because intgers in both negative and positive but whole no.s in only positive No it is false Whole number = 0, 1, 2, 3, 4, 5..........Integers = ..........., -3, -2, -1, 0, 1, 2, 3,.......So every integer is not whole number.But every whole number is a integer. No. This is because integers contain negative numbers which are not included in whole numbers as whole numbers start from 0 .Examples of integers are -1,-2,-3 etc.... No |
