1. Here are the ingredients needed to make 8 pancakes
100g plain flower
250ml milk
1 egg
50g butter

(a) How much flour is needed to make 20 pancakes?

Here is some nutritional information about the ingredients used to make pancakes.

Description Carb(g) Protein(g) Fat(g)
100g plain flower 76.3 10.3 1.0
100ml milk 4.7 3.3 3.3
1 egg 0.5 5.5 4.4
100g butter 0.1 0.9 81.1

(b) Work out the protein content of 1 pancake

(c) work out the fat content per 100g for pancakes.
You can assume that an egg weighs 44g and that 1ml of milk weighs 1g

Here are the ingredients needed to make 8 pancakes
100g plain flower
250ml milk
1 egg
50g butter

(a) How much flour is needed to make 20 pancakes?
First just work out how many ingredients is required per 1 pancake by dividing each ingredient by 8.

Then, to find how many are required for 20, multiply the ingredients required for one pancake by 20
4. a) 20 / 8 = 2.5
So you need 2.5 times of everything listed for 8 pancakes to make 20 pancakes.
2.5 * 100 = 250g flour

b) Use the nutritional values to work out how much protein is in 8 pancakes and then divide this by 8.

c) work out the weight of the 8 pancakes and how much fat is in them. Divide the weight of the 8 pancakes by a value that will result in 100g. Divide the original fat content by this same value.
