Yes.

just find a common denominator and add like you regularly would with fractions.

It helps to find a common denominator and multiply both sides of the inequality by this common denominator. That way, you have an inequality without fractions.

you have to compare the common fractions

Find the lowest common multiple of the denominators and adjust the fractions accordingly

Addition or subtraction of fractions require "like" fractions: that is, fractions with the same denominator.

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

There doesn't appear to be any fractions there but to find the LCD of fractions is done in the same way as finding the lowest common multiple of numbers.

Yes you do.

Yes.

You first convert them to similar fractions, i.e., to fractions that have the same denominator.* Step one: find a common denominator.* Step two: convert both fractions to equivalent fractions that have that denominator.
