To find a rational number with one decimal place between √17 and √18, we can estimate the decimal values of both square roots:
√17 ≈ 4.1
√18 ≈ 4.2
We can see that 4.15 is a rational number with one decimal place that falls between these approximations. Therefore, 4.15 is a rational number with one decimal place that is between √17 and √18.

Find a rational number between 2 and 2 1/4 using the method of adding the numbers together and dividing by 2. Write the answer as a mixed number.(1 point)
To find a rational number between 2 and 2 1/4 using the method of adding the numbers together and dividing by 2, we first need to convert 2 1/4 to a decimal.
2 1/4 is equal to 2 + 1/4, which is equal to 2 + 0.25, which is equal to 2.25.
Next, we add 2 and 2.25 together: 2 + 2.25 = 4.25.
Finally, we divide the sum 4.25 by 2: 4.25 ÷ 2 = 2.125.
Converting 2.125 back to a mixed number, we have:
2.125 = 2 + 0.125 = 2 + 1/8 = 2 1/8.
Therefore, a rational number between 2 and 2 1/4 using the method mentioned is 2 1/8.
2 1/4 is equal to 2 + 1/4, which is equal to 2 + 0.25, which is equal to 2.25.
Next, we add 2 and 2.25 together: 2 + 2.25 = 4.25.
Finally, we divide the sum 4.25 by 2: 4.25 ÷ 2 = 2.125.
Converting 2.125 back to a mixed number, we have:
2.125 = 2 + 0.125 = 2 + 1/8 = 2 1/8.
Therefore, a rational number between 2 and 2 1/4 using the method mentioned is 2 1/8.
