Carly is making 3and1/2 batches of biscuits if one batch calls for 2and1/3 cups of flour, how much flower will she need

Carly is making 3 and 1/2 batches of biscuits = 7/2 batches

1 batch calls for 2 and 1/3 cups of flour = 7/3 cups

7/2 batches = How many cups?

Cross multiplying you get;

7/2 * 7/3 = 49/6

Simplifying you get;

8 and 1/6 cups of flour.
