Question

Hafida needs 40g of sugar to make 12 biscuits.

She also needs
- three times as much flour as sugar
- two times as much butter as sugar
Hafida is going to make 60 biscuits.
Work out the amount of flour she needs.

Answer 1

To find the amount of flour Hafida needs, we use the ratios given in the question. She needs 120g of flour to make 12 biscuits, and 200g of flour to make 60 biscuits.

Step-by-step explanation:

To find the amount of flour Hafida needs, we need to consider the ratios given in the question. It states that Hafida needs three times as much flour as sugar. Since she needs 40g of sugar, she will need 3 times that amount of flour, which is 3 * 40g = 120g of flour. Therefore, Hafida needs 120g of flour to make 12 biscuits.

Now, let's calculate the amount of flour she needs to make 60 biscuits. Since the amount of flour needed is directly proportional to the number of biscuits, we can set up a proportion: 12 biscuits / 40g of flour = 60 biscuits / x g of flour. Solving for x, we get x = (60 biscuits * 40g of flour) / 12 biscuits = 200g of flour.

Therefore, Hafida needs 200g of flour to make 60 biscuits.
