Answer:

Step-by-step explanation:
First, we change both denominators to the LCM (lowest common multiple) which is 8.

Since the denominators are the same, we can add the numerators.


or it can be written as

$30 = 75%, so divide it by three and you got your 25%, which ia $10.
$10 * 4 = $40.
So the answer is $40.
