420ml= OZ Can you please show the work on how I figure out this problem

Absolutely! Here's how to convert milliliters (ml) to fluid ounces (oz): **Key conversion factor:** * 1 milliliter (ml) = 0.033814 fluid ounces (oz) **Steps:** 1. **Set up a proportion:** Since we know the conversion factor, we can set up a proportion: ``` 1 ml / 0.033814 oz = 420 ml / x oz ``` (where 'x' represents the unknown quantity of fluid ounces) 2. **Cross multiply:** Multiply across the proportion: ``` 1 ml * x oz = 420 ml * 0.033814 oz ``` 3. **Isolate 'x':** Divide both sides of the equation by 1 ml: ``` x oz = (420 ml * 0.033814 oz) / 1 ml ``` 4. **Calculate:** Perform the calculation: ``` x oz ≈ 14.20 oz ``` **Therefore, 420ml is approximately equal to 14.20 fluid ounces.**
