Amanda pours 3/4 of her water into Barbara’s empty bottle. Barbara then pours 3/5 of her water into Charlie’s empty bottle. Charlie then pours 1/2 of his water into David’s empty bottle. If David now has 18 ounces of water, how many ounces does Amanda still have?

8

Step-by-step explanation:

David=18

charlie pours 1/2 which is 18 because that is how many david has and 18 is half of charlies thing. So charli has 36 cause 18 times 2 is 36

CHARLI=36

36 is 3/5 of barbra's so 3 divided by 36 is 12 and ther  are 2 more halfs so 12 times 2 is 24

BARBRA=24

24 is 3/4 of Amandas so you have to do 24 divided by 3 which is 8. so each 4th is 8 and there is one more 4th so it is 8

5.4

Step-by-step explanation:

18 x 2 = 36 .    3/5 of 36 is = to 36 x 3/5 = 21.6 .    21.6 / 4 x 3 = 16.2 .  21.6 - 16.2 = 5.4
