You can write it as a proportion. Let's say the number of jellybeans you want to purchase is n.
n/.50 = 300/x
Multiplying both sides by 0.50 gives you
n = .50*300/x
n = 150/x
At the same rate, you can purchase 150/x jellybeans.
_____
The number will only be an integer if x is one of
1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150.
n/.50 = 300/x
Multiplying both sides by 0.50 gives you
n = .50*300/x
n = 150/x
At the same rate, you can purchase 150/x jellybeans.
_____
The number will only be an integer if x is one of
1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150.
