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
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.
