Answer:
240
Step-by-step explanation:

When doing proportions you multiply the numerator of one fraction by the denomenator of the other. Here the available pair is 19.2 and 25. This means that we multiply 19.2 by 25, which equals 480. The next step is to divide by the remaining numerator or denomenator. Here we divide 480 by 2, which equals 240.
25 is 5×5. it can look like this: 5×5=25 or 5 (5) = 25
