Answer:
120 ml oil
150g onions
1.2 kg potatoes
1.5 litres milk
Step-by-step explanation:
The revipe serves 4 people, but Richard wants to serve 12 people. This is 3x the number of people intended.
So, multiply all the fiven ingredients by 3 as well.
Oil = 40ml x 3 = 120ml
Onions = 50g x 3 = 150g
Potatoes = 400g x 3 = 1200g = 1.2 kg
Milk = 500ml x 3 = 1500ml = 1.5 litres
Hope this helps
150 g onions
1200 g potatoes
1500 ml milk
the recipe makes 4 portions. Richard wants 12.
4×3=12
Multiply the recipe by 3 to get 12 portions.
Open up the parentheses
-7x cancels out on both sides
-12 cancels out on both sides
I hope this helps!
