A shopkeeper bought 150 packets of milk. Each packet contained 250 ml of milk. If one fluid ounce is equal to 30 ml, how many ounces of milk did he buy? Let's answer step by step:
If the shopkeeper bought 150 packets of milk, each packet containing 250ml of milk, all the packets had a total of 250 * 150 = 37500ml. Since one ounce equal 30 ml, the total amount of milk that the shopkeeper bought in oz is 37500 / 30 = 1250 oz of milk. The answer: 1250.
