To determine the fractional part of the pizza that you kept for yourself, we first need to calculate how many slices you gave away.
The total number of slices is 8. You gave:
- 3 slices to your brother Joe
- 2 slices to Emily
- 1 slice to your mom
Now, we add the slices given away: 3 + 2 + 1 = 6 slices
Next, we find out how many slices you kept by subtracting the slices given away from the total slices: 8 - 6 = 2 slices
Now, we want to find out what fraction of the whole pizza these 2 slices represent. Since the pizza was cut into 8 slices, the fractional part you kept is: 2 (slices you kept) / 8 (total slices) = 2/8
We can simplify the fraction: 2/8 = 1/4
So, the fractional part of the pizza that you kept for yourself is 1/4.
The answer is D: 1/4.
