Number of cards of John: J
Number of cards of Alan: A
<span>John and Alan have a collection of x baseball cards:
J+A=x (1)
</span>John has x/4 cards:
J=x/4
<span>What fraction of the cards does Alan have?
</span>
Replacing J by x/4 in the equation (1)
(1) J+A=x
x/4+A=x
Solving for A:
x/4+A-x/4=x-x/4
A=4x/4-x/4
A=(4x-x)/4
A=3x/4
Answer: Alan has 3/4 of the cards
The answer would be C
A) (4+4)/(4x4)=(8)/(16)=1/2
B) 4+4/(4x4)=4+4/(16)=4+(1/4)=4 1/4
C) 4+(4/4)x4=4+(1)x4=4+4=8
There are 5 cents per 1 nickle
there are 1 cents per 1 cent
