Cerrena [4.2K]

Answer:

8

Step-by-step explanation:

To find the largest number of groups she can have, find the largest number that can divide 104 and 88 evenly.

This number is 8, since 8 divides 104 to 13 and it divides 88 to 11.

This means each group will have 13 nickels and 11 dimes.

So, the answer is 8 groups.
