Example 15:  If 1 m 70 cm cloth is required to make a pillow cover. How much cloth is required
                                  to make 48 such pillow covers?
                                                                                                           Calculation
                    Solution:     Length of cloth required to make 1 pillow cover = 1 m 70 cm
                                                                                                                2

                                                                                                                1 . 7  0
                                  Number of pillow covers to be made = 48                                  ×     4  8

                                   Total length of cloth required to make 48 pillow covers                  1 3 6 0

                                               = 1.70 m × 48 = 81.60 m
                                                                                                             8  1 . 6  0
                                  So, 81.60 m of cloth is required to make 48 pillow covers.

                    Example 16:  If 4 bags of wheat weigh 50.280 kg, find the weight of each bag.

                    Solution:     Total weight of 4 bags of wheat = 50.280 kg                             Calculation
                                   Weight of each bag = 50.280 kg  4                                    1  2 . 5  7
                                                                                                        4   5  0 . 2  8  0
                                                          = 12.57 kg                                    – 4

                                  So, the weight of each bag of wheat is 12.57 kg.                       1  0
