Answer:
1.true
2.true
3.false
4.false
Step-by-step explanation:
1st one is true because the whole number are from 0 to indefinite and there are no numbers before zero so there is no predecessor of 0 in the whole number system
2nd one is true because the whole numbers between 21 to 11 or 11 to 21 are ten whole numbers
3rd one is false because the successor of two digit numbers is not always a two digit number for example if we take 99 as two digit number its successor is hundred and hundred is a 3 digit number so it is not necessary to always a two digit number of successor of a two digit number
4th one is false because the predecessor of two digit number is maybe or may not be single digit number if we take an example as 10 the predecessor of 10 is 9 and 9 is a single digit number so it is not necessary it may be or may not be
