How many strange quarks are in a ∑+ particle?

[Tomo-]

Homework Statement

The ∑+ particle is a baryon with strangeness -1.

How many quarks does the ∑+ particle contain?

Homework Equations

How many of the quarks are strange?

The Attempt at a Solution

I know it contains 3 quarks, 2 ups and 1 strange quark but I'm not sure how to work this out, for future reference, I'm just a little confused.

Edit: just realized this is probably in the wrong section - apologies.

A strange quark has a strangeness of -1. You know there are 3 quarks in a baryon and its strangeness is given as -1 so the answer from there should be obvious.
