Solution

To find out how much extra food is needed to feed the second cat, we need to subtract the amount of food needed for one cat from the total amount of food needed for two cats.

The amount of food needed for one cat is 1 2/5 cans each day. This is a mixed number, and we can convert it to an improper fraction for easier calculation. 1 2/5 = 5/5 + 2/5 = 7/5.

The total amount of food needed for two cats is 3 1/2 cans each day. We can also convert this to an improper fraction. 3 1/2 = 6/2 + 1/2 = 7/2.

Now we subtract the amount of food needed for one cat from the total amount:

7/2 (total for two cats) - 7/5 (amount for one cat) = 35/10 - 14/10 = 21/10 = 2 1/10 cans.

So, Kinsley needs an extra 2 1/10 cans of cat food each day to feed the second cat.
