A proportion is an equation with a ratio on each side. It is a statement that two ratios are equal. 3/4 = 6/8 is an example of a proportion. When one of the four numbers in a proportion is unknown, cross products may be used to find the unknown number.
Suppose we have a point X on a segment AB. This point divides the segment into two pieces: AX and XB. It is often important to know the ratio of the lengths of these two segments. this is sometimes referred to as the ratio into which X divides the segment AB.There are two common ways to measure this:ou can compute the ratio Length(AX)/Length(XB), which describes the relative sizes of the two pieces. If X is close to A this ratio is close to 0. As X moves along the segment towards B, the ratio gets increases. When X is at the midpoint of AB the ratio is exactly 1.
