1. you take the 3 decimal place and if it is 0.005 or higher the decimal in the 2nd place goes one up but if lower it stays the same
It is 2.48
141.37
The 2nd decimal place is a 4, so round down: → 0.0471 to 1 dp is 0.0
42.86 the number in 3rd place after decimal (thousandths) is 8 so since 5 or greater round up the 2nd decimal place, which is hundredths (cents)
If the 3rd decimal place is 5 or more, increase the 2nd decimal place by 1, and discard everything after it. If the 3rd decimal place is less than 5, leave the 2nd decimal place alone, and discard everything after it.

you take the 2nd decimal and if it is under 5 you take out the 2nd decimal and leave the 1st decimal the way it is, if the 2nd decimal is 5 and over you add 1 to the 1st decimal with 5.72 it will change to 5.7 but if it was 5.77 it would change to 5.8
By taking a number's 2nd decimal place and seeing if it is .45 or higher.
8.562 Inspect the 3rd decimal place . In this case it is '2'. The rule is for 'n' decimal places , inspect the 'n+1' decimal place. If the 'n+1' decimal place is between 0 & 4 , then leave the 2nd decimal unchanged. If it is between 5 & 9 then add '1' to the second decimal place. Since in this case the third decimaal is '2' ( between 0 & 4), then leave the 2nd decimal place unchanged. at '6'. Hence 8.452 to 2 d.p. is 8.56 .
.01 The 1 there is in the hundredths place.
5.3 Look at the digit in the 2nd decimal place i.e. the '6'. If it is a 5 or greater round the previous digit up.
9.00
Use the 2nd decimal place as the determining digit: it is 4 which is less than 5 so round down: 3.6496 → 3.6 to 1 dp.
