Yes, Sienna can make apple crumble for 6 people. To calculate this, we need to work out the ratio of apples to other ingredients. The ratio of apples to other ingredients in the original recipe is 700g:430g (250g sugar + 180g flour + 40g butter). Sienna has 500g of apples, so the ratio of apples to other ingredients is 500g:430g. This ratio is still greater than 1:1, so Sienna has enough apples to make apple crumble for 6 people.
mathswatch says this is incorrect :(

help!
to serve 6, she will need
6/8 * 700 = 525g of apples.
So, no.
The other ingredients do not matter, since she has plenty of those.
