David drove 634 miles on 26.6 gallons of gas what was his my with rounded to the nearest mile per gallon

The answer is 24 mpg.

If my math is correct, the answer is about 57.14 grams

Step-by-step explanation:

The fact that one kilogram is about 35 ounces is a conversion factor, so if you use that in the equation, it goes something like this

2 ounces /1  x  1 kg/35 ounces x 1000g/1kg

To make the equation balance out, you need to end in grams, which is what the question asks. To get ounces to cancel, you need to use the conversion factor, 35 ounces on the bottom (since ounces over ounces cancels), then you have kilograms left, which you need to convert to grams. You can do this by using the metric system line, which goes Kilo, Hecta, Deca, The unit, Deci, Centi, and milli, each unit increasing by ten as it goes along. Thus, one kilogram equals 1000 grams. Combining this all together, you get 57.14 grams.

Hope this helps!
