Matt has to bake muffins. He uses x eggs for each 200 grams of flour. If he has to use 900 grams of flour how many eggs will he use? I have to set this up as an algebra problem. I am stuck. Our class is just learning this and I don't understand.

Answer 1

carry the units with you, and it will help. You want to convert from grams of flour to eggs

x eggs = 200g
or,

x eggs/200g = 1
you can always multiply by 1 and not change anything.

900 g * x eggs/200g = 900g/200g * x eggs = 9x/2 eggs

Or, since 900 = 9/2 * 200, he will use 9/2 times the eggs used for 200 grams of flour.
