Question

If she makes 2 more batches of batter how many cups of flour will be left?

Answer 1

(I converted the fractions to decimals, but it's easily to convert back if they need to be fractions.)
12-9.25= 2.75
9.25-2.75= 6.50
6.5-2.75= 3.75
3.75-2.75= 1
So she will have 1 cup of flour left after 2 more batches.

Answer 2

If the baker makes 2 more batches she will have one cup of flour left.
