Question

You want to make a large bowl of salad to share with your friends. Your brother eats 1/3 of it before they come over.

Answer 1

Lets think the entire bowl of salad as 1 unit. Now your brother eats one-third. So the remaining salad is 1 minus 1/3 . And now you want to divide the remaining salad evenly among 6 friends. so it is 1-(1/3) divided by 6. To put it in one single expression, it is (1-(1/3)) / 6
