                       3.  Answer the following using repeated subtraction.

                           a.    How many 2s are there in 18? ____            b.   How many 3s are there in 27? ____

                           c.    How many 4s are there in 28? ____            d.   How many 8s are there in 40? ____

                    DivisiOn Using A nUmber Line

                    A number line can be used for division.

                    Let us use the number line to find 10 ÷ 2.

                    Finding 10 ÷ 2 means finding the number of 2s in 10.
                    On the number line, start from 10 and move backwards 2 steps each time to reach
                    0, as shown below.

                    How many jumps have we taken to reach 0? We have made 5 jumps of 2 each.
                    So, 10 ÷ 2 = 5.

                                                                                                                  93
                                                                                                     Division
