Question

John and Alan have a collection of x baseball cards. John has x/4 cards. What fraction of the cards does Alan have?

A. x/3
B. 3x/4
C. 3/4
D. 3x

Answer 1

Let's say Alan had y cards. So because "John and Alan have a collection of x baseball cards" and "John has x/4 cards", we know that

x/4+y = x


Solve this equation for y to find how many cards Alan has (in terms of x)

Answer 2

Ummmm 3x?

Answer 3

close

Answer 4

3x/4?

Answer 5

subtract x/4 from both sides to get


y = x - x/4

Answer 6

x/4 -x = -y
3x/4 = y

Answer 7

good, if you combine x-x/4, you'll get 3x/4

So y = 3x/4
