The document discusses a school barbecue where 140 people will eat chocolate ice cream. It calculates that if each person eats 250 grams of chocolate ice cream, the school will need 35 kilograms total. It further notes that if ice cream comes in 750 gram containers, and each person eats 250 grams, then one container can serve 3 people. With 350 total people and 140 eating chocolate ice cream, they would need 46 2/3 containers of chocolate ice cream.
3. Question A:
140 people will eat chocolate ice cream during the
barbecue. One way to find the answer is to divide 350 by
10, making 1 tenth of 350, then multiply by 4 to make 4
tenths.

4. Question B:
To do this problem you simply need to multiply 140 by
250, making 35,000; this means that assuming each person
eating chocolate ice cream is eating exactly 250 grams, the
school will need 35 kilograms of chocolate ice cream.

5. Extension:
If ice cream comes in 750 gram containers, then assuming
each person is given a flat 250 grams of ice cream, then one
container would be enough for 3 people. This means that
the ratio of people to containers is 3:1, so if there are 350
people, you would need 117 containers of ice cream; 46
and 2/3 of a container for the chocolate eaters, and 70
containers for the people who eat vanilla ice cream.
Afterwards, you would still have 250 grams of ice cream
left over.
