Given:
17.218 - 5.75
Round first to the nearest tenths.
Solution:
In rounding numbers, it must be taken to note that if the number is greater than or equal to 5 then the succeeding number will be added by 1, hence if the number is less than 5, then the succeeding number will remain the same. Tenths place is located at the first digit after the decimal, hence we can round each number by simply looking at the succeeding digits if it is greater than 5 or less than 5.
= 17.2 - 5.6
= 11.6
Final answer:
= 11.6
