To find the height of 50 books stacked on top of each other, we can use the given information and some basic math.

Given:
Height of 3 books = 7.5 cm

First, we need to determine the height of one book. We can do this by dividing the total height of 3 books by the number of books (3).

Height of one book = 7.5 cm / 3 = 2.5 cm

Now, we need to convert the height from centimeters to meters since the answer is required in meters. There are 100 centimeters in 1 meter, so we can convert centimeters to meters by dividing by 100.

Height of one book in meters = 2.5 cm / 100 = 0.025 meters

Finally, to find the height of 50 books stacked on top of each other, we multiply the height of one book by the number of books (50).

Height of 50 books = 0.025 meters/book * 50 books = 1.25 meters

Therefore, the height expressed in meters, of 50 books stacked one on top of each other, is 1.25 meters.
