You cannot add or subtract fractions with unlike denominators because the denominators represent different units or parts, making them not directly comparable. For example, you cannot add 1/4 cup and 1/3 cup of flour as their denominators represent different fractions of a cup. However, you can add or subtract fractions with like denominators because they represent the same units or parts, such as adding 1/4 cup and 1/4 cup of sugar.
