A monolith essential notebook series with a 4:10 ratio indicates that the width of the notebook is 4 units for every 10 units of height. This ratio was favored by Le Corbusier due to its versatility and ease of use in on-site work. A ratio of 4:10 can be simplified by dividing both numbers by their greatest common divisor, which is 2. Thus, the simplified form of the ratio 4:10 is 2:5.
