        Example 2:  Divide 2 L 500 mL by 5.

        Solution:          2 L 500 mL  = (2 × 1000) mL + 500 mL                                   5 0 0
                                         = 2000 mL + 500 mL = 2500 mL                       5 2 5 0 0
                                                                                            – 2 5
                          2500 mL ÷ 5  = 500 mL                                                      0 0

                          Thus, 2 L 500 mL ÷ 5 = 500 mL

        In real life, we come across such problems that involve the calculation of some metric measures.


              Let’s Attempt

        Example 1:   Sumi travels 29 km 60 m by bus and 44 km 850 m by car to reach her house. How
                       much distance is covered in total?

        Solution:      Distance travelled by bus = 29 km 60 m                                    km          m
                       Distance travelled by car = 44 km 850 m                                  1        1
                         Thus, total distance travelled                                         2   9    0   6   0

                              = 29 km 60 m + 44 km 850 m = 73 km 910 m                       + 4    4    8   5   0
                                                                                                7   3    9   1   0

        Example 2:   On a day at a juice shop 53 L 750 mL of juice was sold. If the juice seller sold 28 L
                       more on next day, how much juice was sold on the next day?
        Solution:      Juice sold on first day  = 53 L 750 mL                                     L         mL

                       Juice sold on next day = 53 L 750 mL + 28 L                              1

                         Thus, the juice seller sold 81 L 750 mL of juice on the                5   3    7   5   0
                       next day.                                                             + 2    8    0   0   0
                                                                                                8   1    7   5   0

        Example 3:  A tailor had 15 m of cloth. He used 2 m 50 cm and 2 m 45                            m     cm
                       cm to make two shirts. How much cloth is left now?                                2   5   0
        Solution:      Total length of cloth = 15 m                                                  + 2     4   5
                          Length of cloth used in making two shirts                  m 4    9 cm 10      4   9   5

                         Length of cloth left = 15 m – 4 m 95 cm                   1   5    0   0
                                                    = 10 m 5 cm                –       4    9   5
                       Thus, 10 m 5 cm of cloth is left now.                       1   0    0   5
