Question

In the given figure a circle is divided into 7 equal parts Find the sum of areas coloured in red and yellow. Express in fractional and decimal form.

Answer 1

The circle is divided into 7 parts.
Red part is given as $\frac{1}{7}$
Similarly, the yellow part is represented as $\frac{1}{7}$
Sum of red and yellow parts = $\frac{1}{7}+\frac{1}{7}=\frac{2}{7}=0.285$
Fractional representation = $\frac{2}{7}$
Decimal representation = 0.285
