(i) Find the fraction of the purple-shaded region.
no. of purple-shaded parts=40
total no. of equal parts=100
numeratordenominator
=
no.ofshadedpartstotalno.ofequalparts
=
40100
Substitute values
(ii) Find the percentage of the purple-shaded region.
Percentages are values per a hundred, or x100. The per a hundred is represented by the symbol %.
Since the fraction has a denominator of 100, get the numerator and add a percentage symbol (%).
Percentage
=
40100
=
40%
Convert the denominator into a percentage symbol
(iii) Find the percentage of the yellow-shaded region.
Since percentages amount to a hundred of a value, simply subtract the the percentage of the purple-shaded region from 100% to get the percentage of the yellow-shaded region.
Percentage
=
100-40
=
60%
(i)40100
(ii)40%
