Answer
Dalton said that atoms combine in simple whole-number ratios. If the ratio of atoms of each element in a compound is fixed, then it follows that the ratio of their masses is also fixed. So the law of definite proportions is consistent with Dalton's atomic theory in the way that they are both in proportions, fixed.
