Answer :
16.45 is less than 16.454. The reason is because 16.454 is 4 thousandths more than 16.45 assuming that both numbers are exact numbers. Although it is only a small amount it still makes 16.45 less than 16.454.
we know that
[tex] 16.454=16.45+0.004 [/tex]
so
[tex] 16.45 < 16.45+0.004 [/tex]
therefore
[tex] 16.45 [/tex] is less than [tex] 16.454 [/tex]
because [tex] 16.454 [/tex] is [tex] 4 [/tex] thousandths more than [tex] 16.45[/tex]
the answer is
[tex] 16.45 [/tex] is less than [tex] 16.454 [/tex]
