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 largest $9-$digit number.

Answer 1

There are $0-9$ chips.

For making the largest $9-$digit number we put the largest number on the ten-crore place and the decreasing number on decreasing place value column.

T-C	C	T-L	L	T-Th	Th	H	T	O
$9$	$8$	$7$	$6$	$5$	$4$	$3$	$2$	$1$

Hence, the largest $9$-digit number$=98,76,54,321$.
