Hello. Have you tried anything? Do you have a specific question about this exercise? ?

You have 70 apples. Put them in piles of 5 apples. In each pile of 5, 3 are red--so in each pile 2 are green. Just multiple the number of piles by 2 to get the number of green apples.

Now put the green apples in piles of 7. Each pile has 2 bruised apples. So how many bruised green apples are there?
