1. They are equivalent fractions.

2. They cross-multiply to the same value (a/b = c/d if and only if ad = bc).

How do you find out if two ratios from a proportion?

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."


How can you determine if two ratios form a proportion?

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).

What parts of daltons atomic theory is illustrated by 2 parts of hydrogen and oxygen forming water?

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.
