which of the following is a rational number between 8 and 81/2?
To find a rational number between 8 and 81/2, we can take the average of the two numbers.
8 is equivalent to 8/1.
To add the fractions, we need a common denominator. The common denominator is 2.
8/1 = 16/2
Now, we can find the average:
(16/2 + 81/2) / 2 = (97/2) / 2 = 97/4
Therefore, 97/4 is a rational number between 8 and 81/2.
To find a rational number between 8 and 81/2, we need to find a number that is greater than 8 but less than 81/2.
First, let's convert 81/2 into a decimal. We can divide 81 by 2:
81 ÷ 2 = 40.5
Therefore, 81/2 as a decimal is 40.5.
Now, to find a rational number between 8 and 81/2, we can choose any number between 8 and 40.5.
For example, we can choose 15.
So, the rational number between 8 and 81/2 is 15.
