To find a rational number between 2 and 214 using the method of adding the numbers together and dividing by 2, first add the two numbers:
2 + 214 = 216
Then divide the sum by 2:
216 ÷ 2 = 108
So, a rational number between 2 and 214, using the given method, is 108.
Since 108 is an integer, it can also be expressed as a mixed number as 108 0/1.
Find a rational number between 2 and 214 using the method of adding the numbers together and dividing by 2. Write the answer as a mixed number.

Find a rational number with one decimal place that is between 17−−√ and 18−−√.
To find a rational number with one decimal place between √17 and √18, we need to consider the square roots as decimal approximations.
Approximate the square root of 17:
√17 ≈ 4.12
Approximate the square root of 18:
√18 ≈ 4.24
Now, we need to find a rational number with one decimal place between 4.12 and 4.24. We can do this by taking the average of the two approximations.
(4.12 + 4.24)/2 = 8.36/2 = 4.18
So, a rational number with one decimal place between √17 and √18 is approximately 4.18.
