To compare ratios, compare the products of the outer terms by the inner terms.
Ratios are often classified using the following terms: profitability ratios (also known as operating ratios), liquidity ratios, and solvency ratios.
To write equal ratios multiply both terms by the same number or divided both terms. For example, 2/ 9 is a ratio equal ratio will be 4/18. There is no difference between equal ratios and equivalent ratios.
equivalent ratios
The products of the diagonal terms of two ratios is known as the cross product. This term is more often used in reference to vectors, however.
The two ratios are said to be equal when even if we multiply both terms by the same number or divided both terms , the equivalent fraction or simplest fraction is the same.

Yes, they can.
Fractions and ratios sometimes need to be reduced to lower terms. Numbers never do. In fact, "lowest terms" is meaningless when you're talking about a number.
3 to 4 is the lowest terms of the ratios 6 to 8, 9 to 12 and 12 to 16.
when a number of ratios give the same answer after solving the ratios the ratios are said to be equivalent ratios
If the nth term is Tn, the ratios of consecutive terms are Tn+1/Tn for n = 1, 2, 3, ... This will be a constant only for geometric sequences.
