Let be "x" the amount of cups of mayonnaise that he will need to make 1 cup of tuna fish salad and "y" the amount of cups of mayonnaise that he will need to make 9 times the recipe.
Knowing that it takes of mayonnaise to make of tuna fish salad, we can set up the following proportion:
Solving for "x", you get:
So "y" will be:
Substituting the value of "x" into the equation, we get:
it is 1/12 because if there are only a pair you would have 2 dice. and since each die has numbers all the way up to 6 all you have to do is add them. and don't count all the numbers. like add 1+2+3+4+5+6. that's just plain wrong just do add the highest number on each die (6+6)
