The ratios a/b and c/d form a proportion is if their simplified forms are the same, or equivalently, if a*d = b*c

A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "twenty is to twenty-five as four is to five."

There are two equivalent ways (I) Are the two ratios equivalent fractions? If the ratios are a/b and c/d then can you find a number x such that a = c*x and b = d*x. so that a/b = c*x/d*x = c/d This requires x = a/c = b/d (II) Cross-multiply and equate. If a/b = c/d then cross-multiplication gives ad = bc. Also, if ad = bc then a/b = c/d (divide both sides by bd).

The ratio of atoms in different compounds is apparent from the chemical formula. Examples:H2O (water) has 2 Hydrogen for every OxygenH2SO4 (sulfuric acid) has 2 Hydrogen for every 1 Sulfur and 4 Oxygen atoms

well there are different ways to get ratios.. its all depending on what your looking for.
