Answer:6 17/18 hours
Step-by-step explanation:
We are informed that on Monday Katie spent 2 1/6 hours studying while onn Tuesday she spent another 4 7/9 hours studying.
The combined length of time she spent studying will be the addition of the numbers of hours spent studying on Monday and Tuesday. This will be:
= 2 1/6 + 4 7/9
= 2 3/18 + 4 14/18
= 6 17/18
She used a total of 6 17/18 hours studying
1h 15minutes, I converted each time into fractions, 2hours to

and the 8hour to

Step-by-step explanation:
150 = p + 78 ------ you want to get the p to one side and the other number the the other side of the =
(78 - 150) = p (78 - 78) ---- what ever you do to one side you do to the other
72 = p
s - 51 = 12 (same thing as above)
s (-51 + 51) = 12 + 51
s = 63
65 = blank + 7 ( you can put a letter like x or y because they number is not determined yet)
65 = x + 7 (same as above)
( 7 - 65 ) = x ( 7 - 7 )
58 = x
