Hi Emma,
The answer is 2/15 of a lasagna. There are 3 people total (Nash + his 2 friends). That means each will get 1/3 of what's leftover. You can simply multiply 2/5 by 1/3 to get 2/15 as the answer. Remember when multiplying 2 fractions together, you multiply the top two to get the numerator, and you multiply the bottom two to get the denominator. (2x1=2 ; 5x3=15 ; Answer = 2/15).
Hope this helps!
