A. 1 2/3 cheese pizza was eaten
3/4 pepperoni pizza was eaten
In total
The total pizza that was eaten is
[tex]1\frac{2}{3}+\frac{3}{4}[/tex]
Convert the mixed fraction to improper fraction
This gives
[tex]\frac{5}{3}+\frac{3}{4}[/tex]
Add the fractions
[tex]\begin{gathered} \frac{5}{3}+\frac{3}{4} \\ =\frac{20+9}{12} \\ =\frac{29}{12} \\ =2\frac{5}{12} \end{gathered}[/tex]
Therefore the total pizza that was eaten is
[tex]2\frac{5}{12}[/tex]
B. If the total pizzas ordered is 4
The leftover pizza is
[tex]4-2\frac{5}{12}[/tex]
Substract
[tex]\begin{gathered} 4-\frac{29}{12} \\ =\frac{48-29}{12} \\ =\frac{19}{12} \\ =1\frac{7}{12} \end{gathered}[/tex]
Therefore, the leftover pizza is
[tex]1\frac{7}{12}[/tex]
