                            Exercise 4F

                    1.  Find the estimated quotients by rounding the numbers to their highest place.
                        a.  81 ÷ 18              b.  95 ÷ 14              c.  88 ÷ 34              d.  257 ÷ 28

                        e.  402 ÷ 44             f.  1821 ÷ 22            g.  4620 ÷ 48            h.  2004 ÷ 53

                    2.  Match the following columns correctly:
                         Column A                            Column B                              Column C
                         (Division)                         (Rounds to)                     (Estimated quotients)

                        a.  76 ÷ 24                          i.  90 ÷ 30                           I.  5

                        b.  93 ÷ 27                          ii.  300 ÷ 60                        II.  3
                        c.  573 ÷ 42                        iii.  80 ÷ 20                        III.  10

                        d.  305 ÷ 61                        iv.  900 ÷ 90                        IV.  15
                        e.  857 ÷ 93                        v.  600 ÷ 40                         V.  4

                Example 1. There are an equal number of students in each class of Blue Marble School.
                If there are 248 students in 4 classes, how many students are there in each class?

                solution.                                                              6 2

                Number of classes                         =  4                 4     2 4 8
                Total number of students                  =  248                   –  2 4

                Number of students in each class =  248 ÷ 4                               8
                                                          =  62                        –  8

                Thus, the number of students in each class is 62.                        0

                Example 2.  If 7488 kg of rice is filled in 16 sacks equally, find the weight of rice in each
                sack.                                                                                            4 6 8
                solution.                                                                                16    7 4 8 8

                Total quantity of rice               =  7488 kg                                             –  6 4
                Number of sacks                      =  16                                                     1 0 8

                Quantity of rice in each sack =  7488 ÷ 16                                                    –  9 6
                                                     =  468 kg                                                 –  1 2 8
                                                                                                                 1 2 8
                Thus, the weight of rice in each sack = 468 kg.                                                       0
