Chip Making- Multiplication

Mc Cain Rules for chip making:

1 extra small potato = 4 french fries

1 small potato = 8 french fries.

1 standard potato= 12 french fries

1 large potato = 28 french fries

1 super large potato =96 french fries

If you need 120 french fries how many different combinations of potato sizes can you come up with?

Enabling

·        If you need 24 french fries how many different combinations of potato sizes can you come up with?

·        If you need 48 french fries how many different combinations of potato sizes can you come up with?

Extending:

·        If you need 220 french fries how many different combinations of potato sizes can you come up with?

·        If you need 288 french fries how many different combinations of potato sizes can you come up with?

If you have already made 24 french fries what combinations of potatoes could you use so you get a total of 288?
