We can solve this problem using a proportion, as the number of biscuits is directly proportional to the amount of flour used.

Given:

• 120g of flour makes 36 biscuits.
• We need to find how many biscuits can be made with 80g of flour.

Let $x$ be the number of biscuits made with 80g of flour. The proportion is:

$\frac{120g}{36 \, \text{biscuits}} = \frac{80g}{x \, \text{biscuits}}$

Now, cross-multiply and solve for $x$:

$120g \times x = 36 \times 80g$

$120x = 2880$

$x = \frac{2880}{120}$

$x = 24$

Thus, 80g of flour can make 24 biscuits.

3. What amount of flour is required to make just 1 biscuit?
4. If 240g of flour is used, how many biscuits can be made?
5. How would the ratio change if 36 biscuits required more than 120g of flour?

Tip: When dealing with proportional problems, always set up a clear ratio and cross-multiply to find the unknown value.
