Look at the first line on the table.

For 4 s'mores, 8 marshmallows are used.

8/4 = 2

2 marshmallows are used per s'more.

For 4 s'mores, 12 graham crackers are used.

12/4 = 3

3 graham crackers are used per s'more.

For 13 s'mores,

13 × 2 = 26

13 × 3 = 39

26 marshmallows and 39 graham crackers are needed.
