3. The ratio of pink marbles to white marbles in Samara's bag is equal to 1:5. What percent of the bag contains pink marbles?Le below is shaded?

Answer 1

Ratio of pink marbles to white marbles is:
`1:5`

Let the number of pink marbles are denoted by
`p`

and the number of white marbles are denoted by
`w`

Then,

`p:w::1:5`

i.e.,
`(p)/(w)=(1)/(5)`

The percentage of pink marbles contain in bag is given by:
`( (1)/(6) ) * 100`

`=(100)/(6)`

`=16.67\%`
