Answer:
600g of chopped tomatoes
450mL of stock
225mL of red wine
Step-by-step explanation:
You will have to do proportions for all 3 ingredients to make them equal and get the correct amount of each ingredient.
[tex]\frac{Amount/you/have}{Amount/you/need}= \frac{x}{Amount/you/need}[/tex]
The 1st fraction is the beef and the 2nd is the other ingredients.
So, follow the template:
[tex]\frac{300g}{400g}= \frac{x}{800g}[/tex]
Cross multiply:
400x = 240000
240000/400 = 600g of chopped tomatoes
[tex]\frac{300g}{400g}= \frac{x}{600ml}[/tex]
Cross multiply:
400x = 180000
180000/400x = 450mL of stock
[tex]\frac{300g}{400g}= \frac{x}{300ml}[/tex]
Cross multiply:
400x = 90000
90000/400 = 225mL of red wine
