For every 10 patties she cooks, she needs 50 ml of cooking oil. How many pints does she need?

To convert milliliters to pints, we can use the conversion factor that 1 pint is approximately 473.176 ml. If she uses 50 ml of cooking oil for 10 patties, she would need about 0.105 pints (50 ml / 473.176 ml per pint). So, for every 10 patties, she needs just a little over one-tenth of a pint of cooking oil! If she cooks more patties, just remember that the ratio remains the same. For example, if she cooks 20 patties, she would need 100 ml of oil, which translates to about 0.211 pints. It's all about keeping that simple proportionality in mind as you scale up the number of patties!
