Colby adds 1 2/3 cups of flour to his mixing bowl and then realizes he put in too much. he takes1/4 cup of flour back out of the bowl. how much flour did colby's recipe call for?

1  2/3 - 1/4
you need to change the denominator for both
2/3 into 8/12 and 1/4 into 3/12
1  8/12 - 3/12
1  5/12
By subtracting 1/4 from 1 2/3 cups of flour, it's 1 and 5/12 cups. 
Is this what the recipe calls for?
