Answer:
a. Tim has completed a greater amount of work.
b. Together they have completed
part of two projects.
Step-by-step explanation:
Let us assume that the project on which Jaime and Tim are working has x amount of space.
Now, given that Jaime has 5 over 11 space of a project completed while Tim has finished 7 over 13 space of the same project.
Therefore, Jaime has completed
amount of space and Tim has finished
amount of space.
a. Now, (7x) \times 11 > (5x) \times 13
⇒
Therefore, Tim has completed the greater amount of work. (Answer)
b. Together they have completed
amount of space out of 2x amount of space. (Answer)

Step-by-step explanation:
The ratio of nurses to docters a month ago was 3:5. Now, it's 4:5. You can tell that there aren't 4 nurses because 3 => 4 is only one nurse. If you duplicate both ratios (multiply both sides by 2), you get 6:10 (for a month ago) and 8:10 (now). This is correct because 6+2=8. Hope it helps!
