How do I do these

1) A chef is serving soup to guests, each guest gets two ladles of soup, if each ladle is 4oz and the chef has 2 gallons of soup how many guests can he serve? 2) The manager of a fish and chip shop allows 10oz of chips per portion how many portions can he get out of 5 lb of chips? 3) For a breakfast buffet the manager allows 3 oz of scrambled egg per person, if there are 120 guests how much scrambled egg does the chef need to make? The chef uses large eggs, how many eggs and how many dozen eggs does the chef need. (hint- you should have 3 answers here). 4) Homemade burgers need 6 oz of ground beef each, they are then sold for $7.50 each. If the chef has 80lbs of ground beef how much money will he make? x Accessibility: Investigate Focus
