Answer 1

step by step explanation:

largest five digit number=22221

smallest five digit number=11112

now we have to subtract

22221-11112=11109

Answer 2

$Largest \:5 \:digit \: number \: made \: using \\the \: digits \: 1\: and \: 2 \pink {= 22221 }$

$Smallest \:5 \:digit \: number \: made \: using \\the \: digits \: 1\: and \: 2 \blue {= 11112}$

$\red { Difference }\\ = Largest \: number - Smallest \: number \\= 22221 - 11112 \\ = 11109$

Therefore.,

$\red { Required \: differnce} \green { = 11109}$
