3/5 * 240 = ?
I think it should be
240/[1-(3/5)]*(3/5)
=360
First, you need to find out the total number of sandwiches were there, so you divide 240(number of tuna sandwiches) by [1-(3/5)](the fraction of the tuna sandwiches to the total number of sandwiches). Then, after you find the total number of sandwiches there, you multiply the total 240/[1-(3/5)] by the fraction of the number of chicken sandwiches (3/5) and you'll get the answer.
240/[1-(3/5)]*(3/5)

If there were only tuna and chicken sandwiches, then as anonymous indicated:
2/5x = 240
x = 600 total sandwiches.
600 - 240 = ?
I hope that makes it a little clearer. Thanks for asking.
