Answer:
she ate 3/20 of the pie
Explanation:
lets say there are 10 slices.
if she ate 1 slice, then darryl ate 2, then Emily ate 3. That is only 5 total slices.
So what if she ate 2? Darryl ate 4, Emily ate 6. That still doesn't work
But if she ate 1.5 slices, then darryl ate 3, then Emily ate 5.5
1.5+5.5=7
7+3=10
so she ate 1.5 slices out of ten. But 1.5/10 cant be a fraction, so you can make it 15/100 and then simplify it 3/20. :)
