Dave is making cookies for his niece. He wants to make 1/2 batches. If the recipe calls for 2 1/4 cups of
flour for one batch, how much flour will he need to
use for 1 1/2 batches?

2.25 + 4.5 = 6.75 cups of flour

2.25

Step-by-step explanation: 1 batch is already 2.25 in decimal form so just infer from there.. divide 2.25 from .5 and get 4.5 then add to the one batch you've already received .. 4.5 + 2.25 = 6.75 and just convert into a fraction 6 3/4
