Answer:
[tex]3,817,500[/tex]
Step-by-step explanation:
we know that
To Round a number
a) Decide which is the last digit to keep
b) Leave it the same if the next digit is less than [tex]5[/tex] (this is called rounding down)
c) But increase it by [tex]1[/tex] if the next digit is [tex]5[/tex] or more (this is called rounding up)
In this problem we have
[tex]3,817,453[/tex]
We want to keep the digit [tex]4[/tex]
The next digit is [tex]5[/tex] which is [tex]5[/tex] or more, so increase the [tex]4[/tex] by [tex]1[/tex] to [tex]5[/tex]
therefore
the answer is
[tex]3,817,500[/tex]
