To find the answer,we can first find the flour the baker left after making bread by setting an equation:
Let the orginal amount of flour be y
2/5y = 16
y = 16×5/2
y = 80/2
y = 40
There is 40lb of flour originally,after using 16 lb to make bread,he had:
40-16
=24lb
We can then find the muffin he made by dividing the answer above by 2/3:
24÷2/3
= 24 × 3/2
= 36
Therefore, he made 36 batches of muffins.
