convert mixed numbers to percentage

                Example :
                Amira is learning to do the cross stitch. She has completed the cross stitch on
                1 whole piece and   7     on the other piece. What is the percentage of cross
                                             10
                stitch that she has completed?
                

                   1 whole piece = 100 cross stitches

                                         =  100   x 100 %
                                             100

                                         = 100 %

                   7  piece = 70 piece   = 70 cross stitches
                 10             100       
                                                 =  70    x100 %
                                                    100

                                                                = 70 %

                                                100 % + 70 % = 170 %
