Answer:
A is equal to 15 units, the value of B is 3 units.
Explanation:
If A and B are inversely proportional, it means that their product remains constant. In this case, we can set up the equation:
A * B = k
where k is the constant of proportionality.
Given that when A is 5 units, B is 9 units, we can substitute these values into the equation:
5 * 9 = k
k = 45
Now, we can use this value of k to find the value of B when A is equal to 15 units:
15 * B = 45
Dividing both sides by 15:
B = 3
Therefore, when A is equal to 15 units, the value of B is 3 units.
I hope this helps :)
