It would help if you proofread your questions before you posted them.

220 - 220/4 = 220 - 55 = 165

Assuming that you mean 20% of the remaining cards,

165 - .2(165) = 165 - 33 = 132

132 - 15 = 117

The answer is 106 :

220÷4 = 55,
220-55=165
220×.20=44.00
165-44=121
121-15=106

Ryan has a collection of 216 baseball cards. He lets his brother have 1/3 of his collection and takes 27 cards to school to give his friends. How many baseball cards remain in Ryan's collection?

To find out how many baseball cards remain in Ryan's collection after sharing with his brother, selling to the baseball card shop, and taking some to school, we can break down the steps:

1. Ryan shares 1/4 of his collection with his brother. To calculate this, we take 1/4 of 220:
1/4 * 220 = 55

2. Ryan sells 20% of his collection to the baseball card shop. To calculate this, we take 20% of 220:
20/100 * 220 = 44

3. Ryan takes 15 cards to school to give to his friends.

Now, let's subtract these quantities from Ryan's original collection:

Starting with 220 cards:
220 - 55 (shared with brother) = 165
165 - 44 (sold to the shop) = 121
121 - 15 (taken to school) = 106

Therefore, after sharing some with his brother, selling some to the shop, and giving some to his friends, Ryan has 106 baseball cards remaining in his collection.
