Answer:
If 9 liters 400 millitres of water is further added, there will be 20 liters of water in the tub.
Explanation:
Given that a tub contains 10 liters 600 millitres of water, to determine, if 9 liters 400 millitres of water is further added to this, what will be total water in the tub, the following calculation must be performed:
1 liter = 1000 milliliters
0.6 liters = 600 milliliters
10.6 + 9.4 = X
20 = X
Therefore, if 9 liters 400 millitres of water is further added, there will be 20 liters of water in the tub.
