a) 1 kg = 10^3 g: multiply by 10^3 to get grams (1.48*10 = 14.8 g)
b) micrometer = 10^-6 m, nanometer = 10^-9 meter, It takes 10^3 nm to make on micrometer, so multiply by 10^3 to get 2.3 nm
c) One ms = 10^-3 s, so 7.25*10^-4 ms = 7.25*10^-7 s; one microsecond = 10^-6 sec, so this is 0.0745 microsecond also
