Make sure the bottom numbers (the denominators) are the same Step 2. Subtract the top numbers (the numerators). Put the answer over the same denominator. Step 3. Simplify the fraction.
Fractions — basic ideas
www.mathcentre.ac.ukand all of these fractions are exactly the same as 3 4. When dealing with fractions, we often use some special mathematical language. Instead of using the words ‘top number’ and ‘bottom number’ we use the words numeratorand denominator. So in 3 4, 3 is the numerator and 4 is the denominator: top number bottom number = numerator denominator.
Algebraic Fractions - University of Plymouth
www.plymouth.ac.ukAlgebraic fractions have properties which are the same as those for numerical fractions, the only difference being that the the numerator (top) and denominator (bottom) are both algebraic expressions. Example 1 Simplify each of the following fractions. (a) 2b 7b2, (b) 3x+x2 6x2. Solution (a) 2b 7b2 = 2×6b 7×b×6b = 2 7b
