Answer:
16,800 Liters
Step-by-step explanation:
Convert 3/4 into eighths, because it was already 1/8 full before the 10,500 liters were added:
3/4= 6/8
Subtract 1/8 from that (because it was already 1/8 full):
6/8-1/8= 5/8
Divide 10,500 by the 5 (because you want how many liters each part is):
10,500/5= 2,100
You know can say that every eighth is 2,100 Liters of water.
Multiply that by the 8 total parts it can hold:
2,100x8= 16,800 Liters
