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)

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
The 2nd decimal place is a 4, so round down: → 0.0471 to 1 dp is 0.0

one hundredth (1/100) is 0.01 (2nd place after the decimal point), so 1.8 rounded to hundredth would be: 1.80
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)
To answer this we need to look at the 2nd decimal place. if the 2nd decimal place is 5 or larger then we add 1 to the 1st decimal place, if it is 4 or less than we do not add 1 and just truncate the rest of the digits. Examples: 12.45 = 12.5 (because 5 needs to be rounded up) 12.31 = 12.3 (because 3 is less than 5) etc So, 342.3846 = 342.4 since 8 is larger than 4
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.

83.33% (rounded to 2nd decimal).
Look at the second(2nd) decimal place. If it is '5' or greater, then add '1' to the first decimal place. . Then drop the rest of the decimals. Hence 16.67 The second decimal place is '7' , so it is greater than '5'. So add '1' to '6' = 7 Hence 16.7 Ignore any more decimals to the right.

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
