Answer:
=2 7/12 is needed on sunday
Step-by-step explanation:
Friday + Saturday + Sunday = total time studying
1 1/4 + 2 2/3 + sunday = 6 1/2
Get a common denominator of 12
1/4*3/3 =3/12
2/3 *4/4 =8/12
1/2 *6/6=6/12
1 3/12 + 2 8/12 + sunday = 6 6/12
Combine terms
3 11/12 + sunday = 6 6/12
Subtract 3 11/12 from each side
3 11/12 - 3 11/12 + sunday = 6 6/12 - 3 11/12
sunday = 6 6/12 - 3 11/12
Borrow 1 from 6 in the form of 12/12
sunday = 5 + 12/12+ 6/12 - 3 11/12
= 5 18/12 - 3 11/12
=2 7/12
