Answer:
3.7452 rounded to 2 decimal places is 3.75
Explanation:
Rounding to decimal places
When rounding using decimal places (dp), the degree of accuracy that is required is usually given. However, there are certain calculations where the degree of accuracy may be more obvious. For example, calculations involving money should be given to two decimal places to represent the pence.
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
Notice that your answer should have the same number of decimal places as the approximation asked for.
Round 0.08513 to 1 and 2 decimal places.
0.0|8513 to 1 decimal place is 0.1
0.08|513 to 2 decimal places is 0.09
Question
Round 249.5046 to 1, then 2 decimal places.
