Estimate what part of the figures is coloured and hence find the per cent which is coloured.

Explanation

(i) In this figure, one part out of four parts is coloured. So the fraction of coloured
part is `1/4`
. Convert the fraction into percentage by multiplying the
fraction
with 100.
Percentageof coloured part
`=(1/4)xx 100`
`=25%`
(ii) In this figure, three parts out of five parts are coloured.
Hence the fraction of
coloured parts is `3/5`

Percentageof coloured part = `(3/5)xx100`

=60%
(iii) In this figure, three parts out of eight parts are
coloured. Hence the fraction ofcoloured parts is `3/8`
Percentageof colouredpart=`(3/8)xx100`
`=37.5%`
