Final answer:
After Lily ate 4 sections of an orange divided into 10 equal sections, Manny and Emma ate 1/6 of the remaining section.
Step-by-step explanation:
First, we need to find out how many sections were left after Lily ate 4 sections. Since the orange was divided into 10 equal sections and Lily ate 4, there are 10 - 4 = 6 sections remaining.
Next, Manny and Emma both ate the remaining section, which means they ate 1 out of the 6 sections. We can represent this as a fraction by writing 1/6.
Therefore, Manny and Emma ate 1/6 of the orange.
