A recipe that serves two people calls for 1,600 milligrams of baking soda. You want to make enough for 10 people. How much baking soda do you need in grams

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

10/2=5

5 x 1600 = 8000 milligrams

= 8 grams
