Question

Abby practiced for 11/12 of an hour and Lauren practiced for 2/3 of an hour. How long did they practice on Wednesday

Answer 1

2/3 equals 8/12

11/12 plus 8/12 will give you the improper fraction of 19/12.

19/12 also equals
1 7/12.

Answer 2

You first have to equalize all of the denominator

2/3 will be equal to :  8/12

Total of their practice time would be :

11/12 + 8/12    = 19/12 hours

Hope this helps
