Question

You have a 20 - ounce bottle of juice. You pour out 1/4 of the bottle to share with a friend. If you pour out 3 ounces for yourself,what fraction of the 20 ounces will be left in the bottle?

Answer 1

Answer:

3/5

Step-by-step explanation:

You have a 20 ounce bottle. You pour out 1/4 of it.

20 x 1/4 = 20/4 = 5   You pour out 5 ounces.

20 - 5 = 15 ounces

If you pour out 3 ounces for yourself,  15 - 3 = 12

what fraction of the 20 ounces (original or total amount) will be left in the bottle?

12 ounces is left after pouring out 1/4 of the bottle for your friend and 3 ounces for yourself. 20 ounces was the total amount you first had in the bottle. The fraction that is left is calculated by dividing the amount left (12) by the total (20)

12/20  BUT each number can be divided by/reduced by 4, so dividing each number by 4  (12/4 = 3, 20/4 =5) gives 3/5.

3/5
