1. 
a) metres to centimetres :
 multiply length by 100
b) metres to millimetres:
multiply length by 1000
c) kilograms to grams:
multiply the mass value by 1000
d) litres to millilitres :
multiply volume by 1000
2.
a) 3 m = 3× 100 = 300 cm
b) 28 cm = 28 × 10 = 280 mm 
c) 2.4 km = 2.4 × 1000 
 = 24 × 10^-1 × 10^3
 = 24 × 10^2 =2400 m
d) 485 mm =485 / 10 
 = 485 / 10 ^1
 = 485 × 10 ^-1
 = 48.5 cm
e) 35 cm = 35 / 100 
 = 35 /10^2
 = 35 × 10 ^ -2
 = 0.35 m
f) 2.4 m = 2.4 / 1000 
 = 24 × 10 ^-1 / 10^3
 = 24 × 10^-1 × 10 ^-3
 = 24 × 10 ^ -4
 = 0.0024 km
g) 2495 mm = 2495 /1000
 
 = 2495 /10^ 3
 = 2495 × 10 ^-3
 =2.495 m
 
 
        
             
        
        
        
This is correct, because it takes 27 minutes to get home so it will probably be about 30 minutes.
