Answer:
Both are wrong.
Step-by-step explanation:
We have that:
Both decomposed the fraction [tex]\frac{13}{8}[/tex] into a sum of fractions. Whoever's decomposition sum has a value of [tex]\frac{13}{8}[/tex] is correct.
David:
[tex]1 + \frac{1}{8} + \frac{3}{8} = \frac{8}{8} + \frac{1}{8} + \frac{3}{8} = \frac{8+1+3}{8} = \frac{12}{8}[/tex]
[tex]\frac{12}{8} \neq \frac{13}{8}[/tex], which means that David is wrong.
Patti
[tex]\frac{4}{8} + \frac{2}{8} + \frac{5}{8} = \frac{4+2+5}{8} = \frac{11}{8}[/tex]
[tex]\frac{11}{8} \neq \frac{13}{8}[/tex], which means that Patti is wrong.
So the answer is that both are wrong.
