Answer 1

Answer:

To round to a decimal place:

look at the first digit after the decimal point if rounding to one decimal place or the second digit for two decimal places

draw a vertical line to the right of the place value digit that is required

look at the next digit

if it's 5 or more, increase the previous digit by one

if it's 4 or less, keep the previous digit the same

remove any numbers to the right of the line

Examples

Round 248.561 to 1 decimal place, then 2 decimal places.

248.5|61 to 1 decimal place is 248.6

248.56|1 to 2 decimal places is 248.56
