3e) Give a number that rounds to 11.8 when rounded to the nearest tenth.

To find a number that rounds to 11.8 when rounded to the nearest tenth, you'll want to look at the range of numbers that fit this criterion. The numbers that round up to 11.8 extend from 11.75 to just below 11.85. So, any number in that range, such as 11.76 or 11.83, will perfectly round to 11.8! Now, if you want to play around with more rounding examples, consider how different decimal places change the outcome. For instance, rounding to the nearest whole number would give you a totally different result! It's fascinating how just a simple shift in focus can lead to diverse answers and insights.
