If 5kg of beef is used to prepare beef stroganoff for 40 customers, how many kilograms of beef will be used to prepare same for 6 customers?

To find out how much beef will be needed to prepare beef stroganoff for 6 customers, we can use a proportion. We know that 5kg of beef was used to prepare the dish for 40 customers, so we can set up the following proportion: 5kg / 40 customers = x kg / 6 customers To solve for x, we can cross-multiply: 40 customers * x kg = 5kg * 6 customers 40x = 30 x = 30/40 x = 0.75 kg Therefore, to prepare beef stroganoff for 6 customers, we will need 0.75 kg of beef, which is equivalent to 3/4 kg of beef. So the correct option is 3/4 kg.
