Robert slices a large loaf of bread to make 12 sandwiches. he made 3 turkey sandwiches and 5 veggie sandwiches. the rest are ham. what faction of the sandwiches did robert maked are ham? what is it in simplest form? ?

We already know that there are 12 sandwiches.

If there are 3 turkey and 5 veggie then there's 8 out of 12 sandwiches that aren't ham.

12 sandwiches - 8 non-ham sandwiches = 4 ham sandwiches

Now we know there are 4/12 ham sandwiches

We need to simplify this now.
4/12 can be divided by 4

4 goes into 4 1 time and 4 goes into 12 3 times making the answer 1/3

1/3 of the sandwiches are ham.
