Step-by-step explanation:
Peter wants to make tarts and to make tarts, he needs 2/5 of a cup of flour per batch of tarts.
Peter has 8 cups of flour.
The number of batches of flour that he can make is given as the number of cups of flour divided by the number of cups per batch.
That is:
N = 8 ÷ 2/5
N = (8 * 5) / 2 = 40 / 2 = 20 batches
Peter can make 20 batches.
