Answer 2

Answer:

ix) false

x) true

Step-by-step explanation:

ix) predecessor = the real no. -1

for example if we take 10 as a two digit no. then it's predecessor would be 9, so it's false that predecessor of a 2 digit no. is never a single digit no.

x) successor = the real no. + 1

for example if we take a 2 digit no. say, 10 then it's successor will be 10+1 i.e. 11 so we can say that the successor of a 2 digit no. is always a two digit no.
