    I don't know how to work these two out?

    So for the first one, because no other ingredients are listed, you use the milk as your determining factor. If 10mls of milk makes 12 shortcakes. Then we can divide the total we have by the total required e.g. 25mls/10mls=2.5 so this means we can make 2.5 times the total for 12 shortcakes. 2.5x12=30.

    For the second part we use the same process but now we have four ingredients. We must find the greatest number we can make which will be determined by the ingredient with the least production potential. For example 500g of sugar would slow us to make 10 batches of 12 shortcakes. However we only have enough butter for 5 batches of 12. This was done using the same method as before for each ingredient separately.

    Sugar: 500g/50g=10 batches of 12. 10x12= 120 shortcakes

    Butter: 1000g/200g=5 batches of 12. 5x12= 60

    So on and so forth.

    This leaves us with the most cookies that can be made being 60 as both the butter and flour will run out first (refer to butter equation above).

    Hope this helps!
