Answer:
[tex]387,169.1[/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]387,169.138383[/tex]
We want to keep the digit [tex]1[/tex]
The next digit is [tex]3[/tex] which is less than [tex]5[/tex], so no change is needed to [tex]1[/tex]
therefore
the answer is
[tex]387,169.1[/tex]
For this case we must round the following expression:
[tex]387169.138383[/tex]
From right to left we have:
[tex]3 <5[/tex] then we have:
[tex]387169.13838[/tex]
[tex]8> 5[/tex] then we have:
[tex]387169.1384[/tex]
[tex]4 <5[/tex] then we have:
[tex]387169.138[/tex]
[tex]8> 5[/tex]then we have:
[tex]387169.14[/tex]
[tex]4 <5[/tex]then we have:
[tex]387169.1[/tex]
