Lara works out $112.4 \div 16$ . She writes:

This is my $16$ times table.

$1$	$2$	$3$	$4$	$5$	$6$	$7$	$8$	$9$	$10$
$16$	$32$	$48$	$64$	$80$	$96$	$112$	$128$	$144$	$160$

I can use the table to work out the division like this:

$16) 112 . 4^{4} 0^{8} 0 (7.25$

So, $112.4 \div 16 = 7.25$ . Explain the mistake that Lara has made.
