[tex] \frac{8}{8} [/tex] is the full pizza
So to solve it, you need to minus the amount that Lou ate from the whole pizza
So it would be [tex] \frac{8}{8} - \frac{6}{8} [/tex] [tex]= \frac{2}{8} [/tex]
To reduce to the lowest terms, you would find the greatest common factor for both the numerator(top) and the denominator(bottom) so 2 is a common factor
2÷2=1 and 8÷2=4
So your answer would be [tex] \frac{1}{4} [/tex]
Answer: [tex] \frac{1}{4} [/tex] is the fraction of the pizza left over
