In nature, each species has normal proportional relationships between the parts; thus a human head is about 1/8 of a person's height and the distance across outstretched arms is equal to the height of the body. Proportion implies that two (or more) items are similar, differing only in magnitude. The centre lines are extended by a short distance beyond the outline. While it refers to the congruity of various parts of a building due to analogous ratios, the term proportion system also characterizes a geometric construction that supplies an underlying order of regulating lines for the plan or facade of a building. For example, ⅘ is a ratio and the proportion statement is 20/25 = ⅘. Conversely, the programs with the lowest proportion of international students were engineering physics and geological engineering, at 9.2 per cent and 9.3 per .
