Old Man Withers just died. He left his collection of baseball cards to his two sons. Bill got 55% of the collection and his brother Bob received the rest. How many cards did Bill receive if Bob received
360 cards, then how many cards did Bill as inheritance from his father?

Step-by-step explanation:

Bill = 55% of the entire collection

Bob = 45% of the entire collection (Since we know 100 - 55 = 45)

We are also told that Bob received 360 cards.

This means that 45% = 360 cards.

First step is to find how many cards is 1%. To do this, divide 360 by 45.

1% of entire collection = cards

This means that since Bill gets 55% of the entire collection, you multiply 8 by 55.

Bill = 8 x 55 = 440 cards.

both equations and proportions are better.
