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.
Here equal would seem to be the stronger term! Two fractions are equivalent when their values are equal; here I think the only reason to use the word equivalent rather than equal is to emphasize that they are two DIFFERENT ways to express the SAME value.
