Question

Give a set of $10$ bingo chips with the numbers $0-9$ to each student.

$\overline{)0}\overline{)1}\overline{)2}\overline{)3}\overline{)4}\overline{)5}\overline{)6}\overline{)7}\overline{)8}\overline{)9}$

Use the chips $0-9$ as follows.

Make the smallest $9-$digit number.

Answer 1

There are $0-9$ chips.

For making the smallest $9-$digit number we put the smaller number $1$ on the ten-crore place and then $0$ on the crore place and the increasing number on the decreasing place value column.

T-C	C	T-L	L	T-Th	Th	H	T	O
$1$	$0$	$2$	$3$	$4$	$5$	$6$	$7$	$8$

Hence, the smallest $9$-digit number$=10,23,45,678$.
