                  example: There are 46 cows in a cowshed. Each cow has 4
                  legs. How many legs are there in all?

                  Solution:                                                   H    t    O

                                                                              1    2
                               Number of cows in the cowshed  =                    4    6
                               Number of legs a cow has                = ×              4

                               Number of legs in all                   =      1    8    4
                               Thus, there are 184 legs in all.
