Solve the equation -2 = k+7/3

Hence, the numbers of friends who went to the game is:

5

Step-by-step explanation:

It is given that:

Several friends each had 2/5 of a bag of peanuts left over from the baseball game.

Let N be the total number of friends who went to the game.

So, the number of bags of peanuts they have is equal to:

(2/5)×N.

The smallest positive integer N for which (2/5)×N is also an integer is N=5.

That means they had 2 bags.

Hence, the number of friends who went to the game is : 5.
