Answer:
11 11/20
Step-by-step explanation:
First determine how much was left after Monday
12 - 1/5
Borrow 1 in the form of 5/5 from the 12
11 +5/5 -1/5
11 5/5 -1/5
11 4/5
Now determine how much is left after Tuesday
11 4/5 - 1/4
Get a common denominator of 20
11 4/5 *4/4 - 1/4 *5/5
11 16/20 - 5/20
11 11/20
91 divide by 6 = 15.16
so, 6 goes 15.16 times into 91
