Question 459722
{{{3/sqrt(7)=3sqrt(7)/(sqrt(7)sqrt(7))=3sqrt(7)/7=1.134}}}


{{{2*sqrt(2)/sqrt(5)=(sqrt(5)*2*sqrt(2))/(sqrt(5)*sqrt(5))=sqrt(5)*2*sqrt(2)/5=((2.24)*2*(1.41))/5=1.38}}}


{{{3sqrt(2)/sqrt(6)=(3*sqrt(2)*sqrt(6))/(sqrt(6)*sqrt(6))=3*sqrt(2)*sqrt(6)/6=(3*(1.41)*(2.45))/6=1.73}}}


{{{2sqrt(5)/sqrt(12)=(2*sqrt(5)*sqrt(12))/(sqrt(12)sqrt(12))=(2*sqrt(5)*sqrt(12))/12=(2*(2.24)*(3.46))/12=1.29}}}
