The answer would be A. 3 1/2.
Explanation
First find a common denominator, which would be 6. You times the top number the same amount of times you times the bottom number to get the common denominator, so now it's 1 4/6 + 1 5/6 now you add, 1+1=2, now you need to add 4 and 5 together, bc they are the top numbers of the fraction. That would be 9 so now the problem is 2 9/6, now we simplify the fraction so that it is 3 3/6 now that simplifies into 1/2 so the answer is 3 1/2

Answer:
a hot water tank was full of hot water before eddy used 15 gallons to wash clothes now there is only 80% of the water. how much water, in gallons, does the hot water tank hold?
720/1 = 1800/x.....720 miles to 1 hr = 1800 miles to x hrs
cross multiply
(720)(x) = (1)(1800)
720x = 1800
x = 1800/720
x = 2.5 (or 2 1/2) hrs <==
