Answer 1

1/3 = 4/12
1/4 = 3/12
7/12 they ate
12-7=5
5/12 is left

Answer 2

Answer:

$\frac{5}{12}$

Step-by-step explanation:

Let the total part of the pizza be x

Nancy ate part of pizza= $\frac{1}{3}$x

Gabe ate part of pizza=$\frac{1}{4}$x

Total part of the pizza is eaten = $\frac{1}{3}$x  +  $\frac{1}{4}$x

Total part of the pizza is eaten=$\frac{3x+4x}{12}$

Total part of the pizza is eaten=$\frac{7x}{12}$

Part of the pizza is left= x - $\frac{7x}{12}$

Part of the pizza is left=$\frac{12x-7x}{12}$

Part of the pizza is left=$\frac{5x}{12}$

Hence, the correct answer is $\frac{5}{12}$
