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.

Let's assume we were given 2 numbers: 15 and 30. their sum is: we want to express it as the product of gcf and another sum.15 is divisible by: 1, 3, 5, 1530 is divisible by: 1, 2, 3, 5, 6, 10, 15, 30the greatest number that appears in 2 series is 15.in this case sum of two numbers can always be written as:
