Here we have to apply cross-multiplication method to add the two fractions 1/8 and 1/3 as given below. L.C.M method If the denominators of the fractions are not co-prime (there is a common divisor other than 1), we have to apply this method.

cross multiplication method via combinatorial approach Sharmila Karim, Haslinda Ibrahim, and Zurni Omar Abstract—In this paper, a new recursive strategy is proposed for determining (n−1)! 2 of
In practice, the method of cross-multiplying means that we multiply the numerator of each (or one) side by the denominator of the other side, effectively “crossing” the terms over. The mathematical justification for the method is from the following mathematical procedure.
(Chapter – 3) (Linear equations in two variables) (Class – X) www.tiwariacademy.com 1 Exercise 3.5 Question 1: Which of the following pairs of linear equations has unique solution, no solution or infinitely many solutions? In case there is a unique solution, find it by using cross multiplication method. Answer 1: Therefore, the given sets of lines are parallel to each other. Therefore
