                  Alternative: To convert mL into L, just write the last 3 digits as mL and the remaining
                  digit or digits as L.

                  For example, 2250 mL = 2 L 250 mL

                          Project
                     Try to know the daily consumption of water in your family. You can start
                     it with a particular activity, such as bathing.

                          ♦ Take your bathing mug and find its capacity. (in L and mL)

                          ♦ How much water do you use while taking a bath?
                          ♦ Who uses the maximum amount of water in your family for taking a bath?

                          ♦ Who uses the minimum amount of water in your family for taking a bath?
                          ♦ Compare them and write the difference in the amount of water they use.

                       the following.

                       (a)  Water in your water bottle = 500 ___  (b)  Tea in a cup = 200 ____
                       (c)  3 pouches of milk = 3 ____                   (d)  Pulses in a pressure cooker = 2 ____

                       (e)  Lemon soda in a glass = 300 ____             (f)  Sanitizer in a bottle = 50 ____
                  2.  Convert litres into millilitres.

                       (a)  2 L                 (b)  5 L                 (c)  7 L                (d)  9 L
