2 literally is 2000ml so if 1 serving is 250ml then ten servings of 250ml would equal 2500ml.
This means that no, 10 servings measuring 250ml each will not fit in a 2 literally bowl because it exceeds 2000ml which equals 2 litters meaning that 500ml of the 2500ml will not fit in the 2 literally bowl.
you divide 66 with 3, that equals 22, then you have three 22. Then you have to take 1 from one of the 22s and give it to the other one, making it 21, 22 and 23
