divide 10 by 2 because 1,600 milligrams of baking soda feeds 2 people. then multiply your quotient by 1,600.
( 10 / 2 = 5 )
5 is your quotient.
multiply 5 and 1,600
1,600 X 5 = 8,000
but you want grams.
there are 1,000 milligrams in a gram.
divide 8,000 by 1,000
8,000 / 1,000 = 8
you need 8 grams of baking soda to feed 10 people
