Answer:

(a) Percentage of girls = 55 $\frac{5}{7}$

(b) Percentage of boys = 44 $\frac{2}{7}$

Step-by-step explanation:

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

Percentage of girls = $\frac{780}{1400}$ × 100%

= 55 $\frac{5}{7}$

Percentage of boys = $\frac{1400-780}{1400}$ × 100%

= 44 $\frac{2}{7}$
