Question

A recipe calls for 1 1/2 cups of flour, 3/4 cup of white sugar, and 1/8 cup of brown sugar. Which of the following mixing bowls can you use to make the recipe: 2-cup, 3-cup, or 4-cup? Justify your answers.

Answer 1

So if I'm going to add this numbers i need them to share a denominator

1 1/2 = 1 4/8 1/8 stays the same 3/4 - 6/8 6/8 + 1/8 = 7/8

7/8 + 1 4/8 = 1 11/8 = 2 3/8 so 3 cups would be the best estimate because the 3/8's are important for the exact mesurement

Hope this helps : )
