Final answer:
Shanice ate 1/3 of the pizza. After subtracting the fraction of the pizza that was left (4/6) from the whole pizza (1 or 6/6), the result is 2/6, which simplifies to 1/3.
Step-by-step explanation:
The student's question concerns the fraction of pizza that Shanice ate. If Shanice started with 1 whole pizza and 4/6 of the pizza is left after she ate, we can infer that she ate the portion that is not left over. To find out what fraction Shanice ate, we subtract the fraction remaining from the total pizza which is 1 (the whole pizza).
Let's calculate:
- Write down the whole pizza as a fraction with the same denominator as the fraction remaining: 1 = 6/6.
- Subtract the fraction remaining from the total: 6/6 - 4/6 = 2/6.
- Simplify the fraction: 2/6 can be simplified to 1/3 by dividing both numerator and denominator by 2.
Therefore, Shanice ate 1/3 of the pizza.
