Explanation:

Step1: Find weight per brick

To find the weight of each brick, we divide the total weight by the number of bricks. The total weight is 525 pounds and the number of bricks is 175. So, we calculate $\frac{525}{175}$.
$525\div175 = 3$ pounds per brick.

Step2: Find weight of 25 bricks

Now, to find the weight of 25 bricks, we multiply the weight per brick (3 pounds) by 25. So, we calculate $3\times25$.
$3\times25 = 75$ pounds.

Answer:

Weight of each brick: 3 pounds
Weight of 25 bricks: 75 pounds
