                    Lesson 1

 

                                                            Problem:                   Multiply the fractions

 

                                                                                                           2x/7 x 3/7

 

Solution                    Look at the fraction carefully

Step 1:   

                                

                                                                                Solution                    Multiply numerator and denominator of fractions with each other and simplify

Step 2:                               

                                                                                                            2x x 3 = 6x  

                                                7    7   49
