Answer 1

(a) Percentage of girls = 55
`(5)/(7)`

(b) Percentage of boys = 44
`(2)/(7)`

Explanation:

To find percentage, we multiply the fraction out of the total by 100%.

Percentage of girls =
`(780)/(1400)` × 100%

= 55
`(5)/(7)`

Percentage of boys =
`(1400-780)/(1400)` × 100%

= 44
`(2)/(7)`
