Designing exercise and solution for conversion. [M1]

Exercise 1 for conversion (Length) 

i) Convert 30791 metre to kilometre                                  ii) Convert 7.5km to cm 

   30791 ÷ 1000  = 30.791                                                       7.5×1000×100 = 750,000

Exercise 2 (Small Units to Large Units)

*Convert to m*

i) 8km to m                          ii) 4.5km to m                                 iii)0.6km to m

   8 × 1000 = 8000                   4.5 × 1000 = 4500                          0.6 × 1000 = 600

*convert to cm*

i) 2m to cm                          ii) 7.3m to cm                                  iii)1.31m to cm

  2 × 100 = 200                        7.3 × 100 = 730                               1.31 × 100 = 131

*convert to mm*

i)5cm to mm                        ii)2.2cm to mm

  5 × 10 = 50                            2.2 × 10 = 22

Exercise for conversion (Mass)

*Convert to mg*

i)74g to mg                          ii)0.13g to mg

  74 × 1000 = 74000               0.13 × 1000= 130

*convert to g*

i)4.3kg to g                    ii)0.650kg to g                     iii)3541mg to g                      iv)466mg to g

  4.3 × 1000= 4300        0.650 × 1000 = 650              3541 ÷ 1000 = 3.541              466 ÷ 1000 = 0.466

*convert to kg*

i)2.4t to kg                           ii)4700g to kg                       iii)69g to kg

  2.4 × 1000 = 2400                4700 ÷ 1000 = 4.7                  69 ÷ 1000 = 0.069

*convert to t*

i)9898kg to t
  9898 ÷ 1000 = 9.898
