Answer:

Whitley owns 2 of the cards

Step-by-step explanation:

In math "of" means to multiply.  So Whitley owns 1/4 the collection meaning we multiply 1/4 by 8 to find how how many he owns.  When multiplying fractions multiply the numerators together and the denominators together.  We can give 8 a denominator of 1 since anything divided by 1 is just itself.  So

1/4 times 8/1=8/4=2

l=5 unit
w=1 unit
h=3 unit
