When can you simplify algebraic fractions?

Fractions often have to be written in their simplest terms. This means they have to be cancelled down until they cannot be cancelled down any more. To do this, look for fractions where the numerator (top number) and the denominator (bottom number) are both multiples of the same times table.

Can you simplify fractions when adding?

When all denominators are alike, simply add or subtract the numerators and place the result over the common denominator. The resulting fraction can be simplified to lowest terms or written as a mixed number.

How do you find like terms in algebraic expressions?

When we look at algebraic terms to find like terms, first we ignore the coefficients and only look if terms have the same variables with same exponents. Those terms which qualify this condition are called like terms. All the given four terms are like terms, because each of them have the same single variable ‘a’.
