Question

0.4837 centimeters rounded to the nearest tenth is what amount in centimeters

Answer 1

for starters:
1.23456...
1=whole numbers
.
2=tenth
3=hundredth
4=thousandth
etc.

To round, you find the potion you want to round to.
Then look at the number to the immediate right.
If that number is 0-4 then you just end at that number.
If that number is 5-9 then you round the previous number up.

For example, rounding to the nearest hundredth:
1.821
Rounds to 1.82 Since 1 is 0-4

1.729
Rounds to 1.73 because 9 is 0-5.
