Answer:
7/15
Step-by-step explanation:
Fraction of the tank which was full when Bill came to work = 4 / 6
Fraction of the tank which was drained during the day = 1 / 5
Fraction of the tank which was full when Bill left work = 4 / 6 - 1 / 5
= 20 / 30 - 6 / 30 (Converting to like fractions)
= 14 / 30
= 7 / 15 (Simplifying)
Thus, 7 / 15 of the tank was full when Bill left work.
