`+)` Explain why Hakan was wrong?
The ratio of the number of boys who like science to the number of boys joined the survey is:
`3 : 10 = 3/10`
The ratio of the number of girls who like science to the number of girls joined the survey is:
`3 : 20 = 3/20`
Because`3/10 > 3/20` so in Hakan's survey, Science was more popular with boys.
`=>` Hakan was wrong
