Thirty-five slices of chocolate cake were sold at the bake sale. If each slice was a tenth of a sake, how many cakes were sold?

By dividing each cake into 10 pieces (1/10), you'd need three and a half cakes to get 35 slices.

To find out how many cakes were sold, we need to divide the number of slices by the number of slices in each cake.

In this case, there were 35 slices of chocolate cake sold, and each slice was 1/10 of a cake.

To find the number of cakes, divide the number of slices by the size of each slice:

35 slices / 1/10 of a cake = 35 slices * 10 = 350 slices

So, 350 slices of cake were sold at the bake sale, which is equivalent to 35 whole cakes.
