Answer:

6/21, 12/42

The other fractions that could represent the amount of time Mary spends doing her math homework is given as:

6 hours/21 hours = 6/21

Also , that could be represented as:

Therefore, the other fractions that could represent the amount of time Mary spends doing her math homework is : 6/21 , 12/42
