Word Proportions

                    Lesson 1

                                 

                                                            Problem:                   Solve the proportion:

                                                                                                30 calls in 5 hours = ______   calls in 4 hours

                                                            Solution                    If there are 30 calls in 5 hours then in 1 hour, the number of calls = 30/5 = 6

Step 1:  

                     

                                                                                Solution                          Number of calls in 4 hours = 6 x 4 = 24

Step 2:                        

 

                                                            Solution                    The answer is: 24 calls

 Step 3:
