Question

A cup of cereal can contain 480 milligrams of salt, which is 20% of the recommended daily amount. What is the recommended daily amount of salt?

Answer 1

0.9kilograms
or
9000grams

Answer 2

Let the recommended percentage of salt be 100

Let the recommended amount of salt be x                                                                                                    

= 20/100 *  x = 480                                      

= 1/5 * x = 480                                        

= x = 480 * 5 = 2400    

⇒ Thus, the recommended daily amount of salt would be 2400 mg.
