Answer:
3/7
Step-by-step explanation:
1/3 = 7/3
so you have 7/3 and 5/7
find the common denominator and
devide the new denominator by the old denominator
and then multiply that number by the numinator of each fraction
and you should get
49/21 and 15/21
then you multiply the 15/21 by 2 because the questions asks you to determine the amount of water left after 2 days
and you get 30/21
then do 49/21 - 30/21 and you should get 19/21
3 goes into 19 and 21 so you devide 19 and 21 by 3 and you get 3/7
101.25 weeks
890-80=810
810/8=101.25
235.24 + 45.58 = 280.82
280.82/2 = 140.41
each check was for $140.41
3,25-2,5=0,75 it is equal to 3/4 so D
