Step-by-step explanation:
Add 1/4 and 1/3.
[tex]\frac{1 \times 3}{4 \times3} =\frac{3}{12}[/tex]
[tex]\frac{1 \times 4}{3 \times 4} =\frac{4}{12}[/tex]
[tex]\frac{4}{12} +\frac{3}{12} =\frac{7}{12}[/tex]
Subtract 7/12 from the whole (1) or (12/12):
[tex]\frac{12}{12} -\frac{7}{12} =\frac{5}{12}[/tex]
[tex]\frac{5}{12}[/tex] of the pizza is left.
