4/3+6/9-7/3=12/9+6/9-21/9=18/9-21/9= -3/9= -1/3
The easiest way to tell if a number is rational or not is to attempt to express it as a fraction. If you can, then the number is rational. If not, then the number is irrational.

Answer:

And the best method for this case is an ANOVA test.
Step-by-step explanation:
For this case we wnat to test if all the mean length of all face-to-face meetings and the mean length of all Zoom meetings are the same. So then the system of hypothesis are:

Alternative hypothesis:
The alternative hypothesis for this case is that at least one mean is different from the others.
And the best method for this case is an ANOVA test.
It has 0 solution there are no meeting points of the two given lines.
