The median average of a set of numbers is the middle number when the numbers are listed in order. If there is an even number of numbers then the median is the mean average of the middle two: There are 2 numbers, therefore the median is the mean average of the middle two, which are the 1st and the 2nd → median = (98 + 101) ÷ 2 = 99.5

Oh, dude, you're hitting me with the math questions now? Okay, so the mean is like the average, which is 80. The mode is the number that appears most often, which is 66. The median is the middle number when they're all lined up, which in this case is also 78. And the range is just the difference between the highest and lowest numbers, so that's 32. Math lesson over, can we go back to talking about snacks now?
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 98, exactly as in the question.
