                  Example 3: Subtract 136 L 540 mL from 200 L.

                  Solution:  Arrange the given measures in the columns of L and mL and then subtract.

                                 Step 1: Subtract millilitres.

                                           540 mL cannot be subtract from 0 mL.                        L           mL
                                                                                                       9   9    9
                                           So, we regroup litre and millilitre.                    1 10 10      10 10

                                           We can write 200 L as 199 L and 1000 mL                 2 0 0        0 0 0
                                           Now, 1000 mL – 540 mL = 460 mL                       – 1 3 6         5 4 0

                                           Write 460 under the mL column.                              6 3      4 6 0

                                 Step 2: Subtract litres.

                                           199 L – 136 L = 63 L

                                           Write 63 under the L column.

                                 Thus, 200 L – 136 L 540 mL = 63 L 460 mL
