you have a 20 ounce bottle of juice. you pour out 1/4 of the bootle to share with a friend. if you pour out 3 ounces for yourself, wheat fraction of the 20 ounces will be left in the bottle?
Well, think about it
1/4 of the 20 ozĀ bottle is 5 ounces
So you gave 5 ounces to a friend
Then, you took 3 ounces for yourself
So 5 ounces+ 3 ounces= 8 ounces
You used 8 ounces
So 20-8=12
The fraction would be 12/20
And if you simliply it, you get 3/5
You have 3/5 oz of juice or soda left on that bottle
2020 - 5/20 = 15/20 This is the amount that you poured to your friend
15/20 - 3/20 = 12/20 This is the amount that you drank
12 ounces is what is left
