                           Think and Answer

                        A snail can crawl 30 inches in 5 minutes. If the snail crawls at this
                        speed in one direction, how far will it travel in 1 minute?

                  Division as rEpEatED subtraction

                  Mahi has 20 laddoos. She wants to divide them equally amongst the 4 children. She starts
                  by giving one laddoo to each children.

                                                                                  total laddoos

                                                                   20                                                   16
                  Step 1:                                        –  4 Step 2:                                          –  4
                                                                   16                                                   12

                                                                   12                                                    8
                  Step 3:                                        –  4 Step 4:                                          –  4
                                                                                                                         4
                                                                    8
                                                                                                                         4
                  Step 5:                                                                                              –  4
                                                                                                                         0

                  No more laddoos are left for distribution. Thus, each child gets 5 laddoos. Here, we
                  subtract 4, five times from 20. So, we can say that 20 ÷ 4 = 5.
                  Thus, division is a repeated subtraction.

                           Quick Check

                      divide the following using repeated subtraction and find the answer.

                      1. 93 ÷ 31 =                   2. 32 ÷ 8 = _______          3. 420 ÷ 105 = _______

                                   93                      –                            –
                            –                1
                                   62                      –                            –
                            –                2
                                   31                      –                            –
                            –                3
