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 $\frac{2}{7}$

12. (x-√3)(x+1) = x² + (1-√3)x - √3

13. (x+2)(x²+4) = x³ + 2x² + 4x + 8

14. (3x³ + 6x² - 5x + 12) ÷ (x-3)

= [(x - 3)(3x² + 15x + 40) + 132 ] ÷ (x-3)

Quotient = 3x² + 15x + 40
Remainder = 132
