Answer:
The answers are:
- nearest tenth: 243.9
- nearest hundredth: 243.88
- nearest ten: 240.00
- nearest hundred: 200.00
Step-by-step explanation:
In order to determine the answer, we have to know about notation numbers.
In any number, every digit has a notation, depending on its position.
I have attached an image that shows some notation numbers.
Also, if we want to round the number, we have to see the position of the cut and the next digit.
There is a rule:
If the "next digit" is equal or greater than 5, we have to increase "the cut number" in one unit.
If the "next digit" is lesser than 5, "the cut number" does not change.
In this case, for 243.875:
nearest tenth:
cut number=8
next digit=7
rounded number=243.9
nearest hundredth:
cut number=7
next digit=5
rounded number=243.88
nearest ten:
cut number=4
next digit=3
rounded number=240.00
nearest hundred:
cut number=2
next digit=4
rounded number=200.00
