Here is a list of what you need to make 20 buns:

- 100g butter
- 150g flour
- 200g sugar
- 4 eggs

Work out what you need to make 30 buns

Please help.
Thank you x

Multiply the amount of each ingredient by 1.5

Multiply the amount of each ingredient by 1.5

Or Divide each item by 2 to get what you need to make 10. then add that to the 20 to give you 30.

To determine the ingredients needed to make 30 buns, you need to calculate the ratios based on the given information for 20 buns.

Let's calculate the ratio of each ingredient first:

Butter:
For 20 buns, you need 100g of butter.
The ratio of butter to the number of buns is 100g/20 = 5g/bun.

Flour:
For 20 buns, you need 150g of flour.
The ratio of flour to the number of buns is 150g/20 = 7.5g/bun.

Sugar:
For 20 buns, you need 200g of sugar.
The ratio of sugar to the number of buns is 200g/20 = 10g/bun.

Eggs:
For 20 buns, you need 4 eggs.
The ratio of eggs to the number of buns is 4/20 = 0.2 eggs/bun.

Now let's calculate the ingredients needed for 30 buns:

Butter:
Multiply the ratio of butter per bun (5g/bun) by 30 buns:
5g/bun * 30 buns = 150g of butter.

Flour:
Multiply the ratio of flour per bun (7.5g/bun) by 30 buns:
7.5g/bun * 30 buns = 225g of flour.

Sugar:
Multiply the ratio of sugar per bun (10g/bun) by 30 buns:
10g/bun * 30 buns = 300g of sugar.

Eggs:
Multiply the ratio of eggs per bun (0.2 eggs/bun) by 30 buns:
0.2 eggs/bun * 30 buns = 6 eggs.

To make 30 buns, you will need the following ingredients:
- 150g butter
- 225g flour
- 300g sugar
- 6 eggs.

Please note that this calculation assumes a proportional increase in the ingredients. It's always best to adjust the recipe according to your taste preferences and any specific instructions provided.

To work out what you need to make 30 buns, we can use a simple proportion calculation.

Here's how you can do it:

1. Determine the ratio of buns to each ingredient: Calculate the ratio of the number of buns (30) to the number of buns in the original recipe (20). In this case, the ratio is 30/20 or 3/2.

2. Multiply the ratio by the amount of each ingredient in the original recipe:

- Butter: Multiply 100g by the ratio (3/2). The calculation is: 100g * (3/2) = 150g.
Therefore, you will need 150g of butter to make 30 buns.

- Flour: Multiply 150g by the ratio (3/2) to get the new amount. The calculation is: 150g * (3/2) = 225g.
So, you will need 225g of flour to make 30 buns.

- Sugar: Multiply 200g by the ratio (3/2) to get the new amount. The calculation is: 200g * (3/2) = 300g.
Thus, you will need 300g of sugar to make 30 buns.

- Eggs: Multiply 4 eggs by the ratio (3/2) to get the new amount. The calculation is: 4 * (3/2) = 6 eggs.
Therefore, you will need 6 eggs to make 30 buns.

So, to make 30 buns, you will need:
- 150g butter
- 225g flour
- 300g sugar
- 6 eggs.
