 \small \purple{let \: assume \: length \: of \: the \: pencil \: is \: x}

 \small  \red{as \: per \: que. \: portion(length) \: of \: black \: in \: pencil} =  \frac{x}{8}

remaining \: portion = x -  \frac{x}{8}  =  \frac{7x}{8}

so \: white \: portion =  \frac{1}{2}  \times  \frac{7x}{8}  =  \frac{7x}{16}

so \: remaining \: portion =  \frac{7x}{8}  -  \frac{7x}{16}  =  \frac{7x}{16}

 \green{as \: per \: question}

 \frac{7x}{10}  = 3.5
