Black=1/8ofx=x/8;remaing=8x-x/8=7x/8
White=1/2of remaining=1/2of7x/8=7x/16
Blue=7/2cm
So x/8+7x/16+7/2=x
2x+7x+56/16=x
9x+56=16x
56=16x-9x
X=56/7=8cm
Black=1/8ofx=x/8;remaing=8x-x/8=7x/8
White=1/2of remaining=1/2of7x/8=7x/16
Blue=7/2cm
So x/8+7x/16+7/2=x
2x+7x+56/16=x
9x+56=16x
56=16x-9x
X=56/7=8cm
