To prepare 6 chocolate milkshakes, 1 1/2 liters of milk are required. If you want to prepare only 3 and a half milkshakes, how many liters of milk are needed? what is the r: 1/4 1/8 7/4 7/8

To find out how many liters of milk are needed for 3 and a half milkshakes, we can set up a proportion using the given information. We know that 6 milkshakes require 1 1/2 liters of milk. Let's set up the proportion: 6 milkshakes / 1 1/2 liters = 3.5 milkshakes / x liters To solve for x, we can cross multiply: 6 * x = 3.5 * 1 1/2 Multiplying both sides: 6x = 3.5 * 3/2 Simplifying: 6x = 10.5/2 Dividing both sides by 6: x = 10.5 / (6 * 2) x = 10.5 / 12 Simplifying: x = 7/8 Therefore, for 3 and a half milkshakes, you would need 7/8 liters of milk.
