Answer 1

To brew a cocoa drink for 45 people, Boss Lin needs 0.35 kilograms of cocoa powder and 1800 milliliters of water.

Step-by-step explanation:

To brew a cocoa drink for 45 people that requires 350 grams of cocoa powder and 1.8 liters of water, Boss Lin needs to determine how many kilograms of cocoa powder and milliliters of water are needed. To find the amount of cocoa powder needed, divide 350 grams by 1000 to convert it to kilograms. To find the amount of water needed, multiply 1.8 liters by 1000 to convert it to milliliters.

Cocoa powder:

350 grams ÷ 1000 = 0.35 kilograms

Water:

1.8 liters × 1000 = 1800 milliliters
