To determine how much pizza is left after consuming 1/5 of what was initially available, start with the amount that is left: 3/5 of the pizza.

When you eat 1/5 of the pizza, you need to subtract this amount from the 3/5 that remains. The subtraction of fractions can be performed as follows:

1. **Set up the calculation**: 3/5 - 1/5.

2. **Subtract the numerators**: Here, you subtract 1 from 3, which gives you 2. The denominator remains the same, which is 5.

3. **Result**: This calculation results in 2/5 left of the pizza.

Therefore, the amount of pizza left after eating 1/5 of it is indeed 2/5. This answer correctly reflects the subtraction of the portions of the pizza, showing the correct understanding of working with fractions.
