Answer:
35mL oil, 90g onions, 600g potatoes, 500mL milk
Explanation:
The recipe makes 24 portions.
Richard wants to make 6 portions.
To start, we have to find the relationship between 24 and 6.
24/6=4
This means that the recipe is 4 times the amount Richard wants to make.
In other words, Richard wants to make 1/4 of the recipe.
We can solve this by dividing each ingredient by 4 or multiplying it by 1/4 to find the amount Richard needs.
Oil: 140/4=35mL
Onions: 360/4=90g
Potatoes: 2.4/4=0.6kg or 600g
Milk: 2/4=0.5L or 500mL
