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
The simplified forms of the two ratios are the same.The cross products are the same: a/b = c/d if ad = bc
The simplified forms of the two ratios are the same.The cross products are the same: a/b = c/d if ad = bc
The simplified forms of the two ratios are the same.The cross products are the same: a/b = c/d if ad = bc
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."
what are 2 ways you can tell that 2 ratios from a propotion

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).
Theirs diffrent ways to put it in (like in a order)
well there are different ways to get ratios.. its all depending on what your looking for.
The three ways to right ratios are... 1:2 1/2 1 to 2
cross multiplying unit rates horizontal
Dalton's atomic theory is illustrated by the combination of hydrogen and oxygen to form water in two ways: through the law of definite proportions, which states that compounds contain elements in specific ratios by mass, and through the law of multiple proportions, which states that different compounds can be formed by combining the same elements in different ratios.
