Question 1125881
simplify 
(1•05×10^-7)÷(1•68×10^-9)

I am not quite sure, but I guess you have


{{{(1*0.5*10^-7)/(1*68*10^-9)}}}...if yes, then



={{{(0.5*(1/10^7))/(68*(1/10^9))}}}



={{{(0.5/10^7)/(68/10^9))}}}



={{{(0.5*10^9)/(68*10^7)}}}



={{{(0.5*10^cross(9)2)/(68*cross(10^7))}}}



={{{(0.5*10^2)/68}}}



={{{(0.5*100)/68}}}


={{{50/68}}}


={{{25/34}}}
