There are 9 shelves of tins. 6 of the shelves hold 5 tins. 3 of the shelves hold 3 tins. What is the total number of tins on the shelves?

39!

If each shelf is full:

6(5) + 3(3) = ?

To find the total number of tins on the shelves, we can add up the number of tins on each shelf.

First, let's calculate the total number of tins on the shelves that hold 5 tins. Each of the 6 shelves holds 5 tins, so we can multiply 6 by 5 to get 30 tins.

Next, let's calculate the total number of tins on the shelves that hold 3 tins. Each of the 3 shelves holds 3 tins, so we can multiply 3 by 3 to get 9 tins.

Now, we can add the number of tins from each group of shelves together. 30 tins + 9 tins equals 39 tins.

Therefore, the total number of tins on the shelves is 39.
