Final answer:
Ching and his 4 brothers set up a total of 300 computers at their family company.
Step-by-step explanation:
To find the number of computers that Ching and his 4 brothers set up at their family company, we need to divide the total number of computers they set up by the number of people involved. Since they each set up the same number of computers, we can divide the total number of computers by 5 (Ching + 4 brothers). Let's denote the number of computers they set up as 'x':
x/5 = 60
Multiplying both sides of the equation by 5, we get:
x = 300
Therefore, Ching and his 4 brothers set up 300 computers at their family company.
