A proportion occurs when two ratios are forced to be equal to each other. This selection will allow you to
find a second ratio that is in the same proportion as the first.
Since a ratio is made up of two numbers, and a proportion compares 2 ratios, we ’ ll be dealing with 4 numbers here, 2 for each ratio.
The proportion below can be stated as: "a is to b as c is to d." This can also be written as a:b::c:d, or in frational form as a/b=c/d, which is how the fill in blanks appear below. |
