15/2 + 5 as a fraction

Learn how to find what is 15/2 plus 5 in fraction form just in a few minutes. We have covered the easiest method to write 15/2 + 5 as a fraction and decimal.

Summary: 15/2 plus 5 = 25/2
Since both fractions have unequal denominators, 15/2 plus 5 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 15/2 and fraction 5 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 2 and 1. 2 is the LCM of 2 and 1. Multiplying the LCM 2 with the numerators and denominators of both fractions (15/2 x 2/2) + (5 x 2/2), and simplify further in order to have the common denominator. So the equivalent fraction for 15/2 is 15/2 and for 5 is 10/2. By simplifying this fraction addition 15/2 + 10/2, it becomes 25/2.
