Answer:
A recipe uses 250 mL of milk for every 300 g of flour.
For making a bigger batch using 600 g of flour, let the amount of milk be x mL.
Now we should solve for x
According to the above problem,
[tex] \frac{250}{300} = \frac{x}{600} \\ x = \frac{600 \times 250}{300} \\ \boxed{ x = 500}[/tex]
★ 500mL of milk should be used to make a bigger batch using 600 g of flour.
