What is the common ratio of 64, 16, 4, 1?

The given numbers in the sequence projects a geometric sequence with a common ratio of 1/4. This is true because 64 *1/4 equals 16 and 16 * 1/4 equals 4. Furthermore, 4 * 1/4 is equal to 1. hence the answer is 1/4

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
