If the fractions have different denominators, rewrite them as equivalent fractions with a common denominator. Then add or subtract the numerators, keeping the denominators the same. For example,. 2 3 + 1 4 = 8 12 + 3 ...

FRACTION REVIEW - Vancouver Island University
services.viu.caIn order to add or subtract, fractions must have common denominators. This is not required for multiplication or division. 1. Adding with Common Denominators To add fractions, if the denominators are the same, we simply add the numerators and keep the same denominators. e.g. 4 1 + 4 2 = 3 Since the denominators are common, simply add the ...

www2.econ.iastate.eduNotice that the denominators of the five fractions are the same and the numerators of the five fractions are 1, 4, 6, 4, 1. The numbers in the numeratorsis a setof binomial coefficients. 1 16 = 4 0 4 16 = 4 1 6 16 = 4 2 4 16 = 4 3 1 16 = 4 4 We can then writethe probability massfunction as Date: August 20,2004. 1
7.4 Integration by Partial Fractions
www.math.uci.eduSince the denominators are equal, it follows that the numerators are equal: x +8 = A(x +2)+ B(x 1) This is a relationship between A, B which holds for all3 x: every value of x gives a valid rela-tionship between A and B. Evaluating at x = 1 and x = 2 gives two very simple expressions: x = 1 : 9 = 3A =)A = 3 x = 2 : 6 = 3B =)B = 2
