A baker starts with 100 pounds of flour. He uses the following quantities in one day: 3 3/8 lb, 18.25 lb, 8.6125 lb, 7 3/4 lb, and three recipes each requiring 5 7/16 lb. How much flour is left at the end of the day?

45.7 lb

Step-by-step explanation:

3 3 /8 = 3.375 lb

18.25 lb

8.6125 lb

7 3/4 = 7.75 lb

5 7/16 = 5.4375 lb

Flour required of 3 recipes = 3 * 5.4375 = 16.3125 lb

                                                           3.3750  +

                                                          18.2500  +

                                                           8.6125   +

                                                           7.7500   +

                                                         16.3125

Quantity of flour used in a day  =   54.3000  lb

Quantity of left at the end of the day = 100 - 54.3

                                                             = 45.7 lb
