Doubling and halving recipes

Use the information below to answer the following questions:

Half of a recipe: you make half a recipe, divide the amount of each ingredient by 2.
Doubling a recipe: you get twice as many servings, so you double the recipe (X2).

Part 1: Below are recipes for caribou stew, bannock and chocolate chip cookies.
Your class is going to make a feast for 30 people. Everyone will most likely have
one bowl of stew, 2 pieces of bannock and 3 cookies. Calculate how many times
you will need to multiply the recipe. Round up – for example if you need to have
2 ½ times more for one recipe – round it up to 3 times more. Also calculate how
much you will need for each ingredient.
