Answer-


\boxed{\boxed{\frac{\widehat{BC}}{\widehat{DE}}=(3)/(4)}}

Solution-

We know that arc length is the product of radius and central angle in radian.

i.e
\text{Arc length}=\text{Radius}* \text{Central angle}

Here,


\theta_(BC)=1.18\ rad,\ \theta_(DE)=2.36\ rad\\\\AD=(2)/(3)AB\Rightarrow AB=(3)/(2)AD

So,


\frac{\widehat{BC}}{\widehat{DE}}=(AB* 1.18)/(AD* 2.36)


=((3)/(2)AD* 1.18)/(AD* 2.36)


=(3* 1)/(2* 2)


=(3)/(4)
