Fractions are alike if they have the same denominators; otherwise they are different.
Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.
They're just different words for the same thing.
Common denominators are created by finding the common multiples of unlike denominators.
Common denominators are common multiples of two or more denominators.
Common denominators are multiples that are being used as denominators. The process to find them is the same.
numerators and denominators are both part of a fraction. the numerator is on top and the denominator is on the bottom. for example, in 2/3, 2 is the numerator and 3 is the denominator
Unit fractions all have the same numerators but the denominators can be different.
