Answer:
Jean poured 4/15 of the contents of the water out which is the equivalent of 267 milliliters (assuming the size of the tank is 1 liter)
Step-by-step explanation:
Let's assume the Tank size is 1 liter
Jean filled the tank 2/3 full
2/3 = 0.667
Jean reduced the water level to 2/5 full
2/5 = 0.40
Jean poured 0.667 minus 0.40 water out of the tank = 0.267
0.267 = 4/15
0.267 of 1 liter = 0.267 x 1000 = 267 Milliliters
