Jasper had a sports card album that held 100 cards he filled 42/100 with football cards and 3/10 with baseball cards what fraction of the album is still empty? Answer choices 28/100 , 45/100 , 55/100, 72/100

Answer 1

To find out what fraction of the album is still empty, we first need to find out how many cards Jasper has already put in the album.

He has filled 42/100 with football cards and 3/10 with baseball cards.

First, we need to convert the fractions to a common denominator: 42/100 = 42/100 and 3/10 = 30/100.

Adding the two fractions together, we get:
42/100 + 30/100 = 72/100

Therefore, Jasper has filled 72/100 of the album.

To find out what fraction of the album is still empty, we subtract the fraction already filled from 100/100:

100/100 - 72/100 = 28/100

Therefore, Jasper still has 28/100 of the album empty.

So, the answer is 28/100.
