To find out the amount of water lost, subtract the final amount from the initial amount.
Initial amount filled = 3/4
Final amount = 3/10
Amount lost = Initial amount - Final amount
Amount lost = 3/4 - 3/10
To subtract fractions, you need to have a common denominator. In this case, the common denominator is 20.
Amount lost = (15/20) - (6/20)
Simplifying the expression:
Amount lost = 9/20
Therefore, the amount of water lost is 9/20.
