A produce stand is packing blueberries into 2/5 pound containers. How many containers can be filled with 60 pounds of blueberrie
Doss [256]

Answer:

24

Step-by-step explanation:

To solve the equation, multiply 60 by 2/5.

[Note: 60 can be written as 60/1]

60/1 x 2/5

Multiply the numerators:

60 x 2 = 120

Multiply the denominators:

1 x 5 = 5

Now simplify:

120/5 = 24

So, the correct answer is 24. I hope this helps! :)
