Question

A picture of dart board is given. Find the percentage of white coloured portion and black coloured portion.

Answer 1

Total sector = 20 

White coloured sector = 10 

Black coloured sector = 10 

Percentage of white : \(\frac{10}{20}\) x \(\frac{100}{100}\) = \(\frac{10}{20}\) x 100 % 

= 50 %

Decimal : \(\frac{10}{20}\) x 100 % = 50 % 

Percentage of black colour : \(\frac{10}{20}\) x \(\frac{100}{100}\) = \(\frac{10}{20}\) x 100 %

= 50 %

Decimal : \(\frac{10}{20}\) x 100 % = 50 %
