To solve this question, we first need to convert both of these values into mixed numbers. 5 [tex] \frac{3}{8} [/tex] becomes [tex] \frac{43}{8} [/tex] and 4 [tex] \frac{1}{4} [/tex] becomes [tex] \frac{17}{4} [/tex]. Now we have to find a LCD. An LCD for 4 and 8 is 8, so now we have to change [tex] \frac{17}{4} [/tex] into something over 8. [tex] \frac{17}{4} [/tex] becomes [tex] \frac{34}{8} [/tex] when you multiply the fraction by the form of 1 [tex] \frac{2}{2} [/tex]. 34 + 43 = 77, so our answer is 77/8 which simplifies to 9 [tex] \frac{5}{8} [/tex].
