Maria practised football for 1 2/5 hours on Friday and 2 2/3 hours on Saturday. How many hours of football did she practice altogether?

4 hours and 4 minutes

Step-by-step explanation:

1 2/5 hours = 1 hour and 24 minutes

2 2/3 hours=2 hours and 40 minutes

add them together

makes 4 hours and 4 minutes

4 1/15

Step-by-step explanation

You do 1 2/5+2 2/3 make the bottom numbers the same. To do that you would times both the top and bottom by the lowest number you can to make them the same 2/5*3 and 2/3*5 which makes it 1 6/15 and 2 10/15 then just add them making it 3 16/15. Then you make the top number lower then the bottom so then you add one to the whole number making it 4 and making the fraction 4 1/15.
