"... other ..." in the question implies that you already know of a few. But you have chosen not to hsare that information. So I have no means of knowing whether my answer is an "other" answer or one that you already know of.
Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same denominator.
Like fractions have the same denominator, unlike fractions don't.
The prefix "un-" in unlike fractions indicates that the fractions are not the same or not similar. It helps to highlight that the fractions have different denominators, making them distinct from each other.
unlike fractions
Unlike fractions are fractions having unlikedenominators, e.g., 1/4 and 1/6.
Like fractions have the same denominators (bottom part of fraction), unlike fractions do not.
unlike fractions
Unlike. Unlike. Unlike. Unlike.
fractions having same denominators are like fractions & others are unlike fractions
"Unlike" fractions.
"Un" means "not." Unlike fractions are not alike.
Unlike fractions have denominators that are unequal, and therefore cannot be added or subtracted. If two fractions need to be added or subtracted they must first be converted to like fractions.
