applebananamangoorange

There are some open markets in England that would like to sell fruit by their weight in lbs (pounds), but we often buy them in kilos.

0.45 kilo = 1 lb
2.20 lb = 1 kilo

You get about 4 apples or 4 bananas in one pound (1 lb).
So, roughly, what would 6 bananas and 4 apples together weigh in kilos?

You get about 6 mangoes in a kilo.
So, roughly, what would 30 mangoes weigh in pounds (lbs)?

You get about 6 oranges in one pound (1 lb).
So, roughly, what would 20 oranges weigh in kilos?
