Question

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

Answer 1

So there are \(x\) total cards?

Answer 2

And John has \((1/4)x\) of those cards...

Answer 3

YES

Answer 4

So what happens when you subtract \(x - (1/4)x\)?

Answer 5

\[
x-(1/4)x = [1-(1/4)]x
\]

Answer 6

Do you know how to subtract a fraction?

Answer 7

sure dont

Answer 8

First you need the denominators to be the same: \[
1= \frac{4}{4}
\]

Answer 9

Now denominators are the same... \[
\frac44 - \frac14
\]The result has the same denominator (bottom)... the numerator (top) is the difference between numerators \[
\frac44 - \frac14 = \frac{4-1}4 = \frac34
\]

Answer 10

So Alan has \((3/4)\) of the total cards... meaning \((3/4)x\) cards.

Answer 11

i already picked that answer, and I got it wrong. so the choices are between A. x/3 B. 3x/4 and D. 3x

Answer 12

I'm thinking it could be 3x/4 though

Answer 13

yes you should know by now it is that one.
