Answer:
Amelie needs 3 17/24 cups of flour in all.
Step-by-step explanation:
If Amelie needs 2 3/8 cups and 1 1/3 cups then 2+1=3
Next, you need to find the gcf of 3 and 8. the Gcf is 24.
So you make 3/8 into 9/24 and 1/3 into 8/24.
Now that they have a common denominator you can just add across.
9 + 8 = 17 so Amelie needs 3 17/24 cups of flour.
