Step-by-step explanation:

$\huge\rm\boxed{\underline{\red{Answer}}}$

8.The product of two numbers is 14.

One of the number is = -8/7 ,

∴ The other number is =

$(14÷\frac{-8}{7})=-14×\frac{7}{8}=-\frac{98}{8}=-\frac{49}{4}$

9.The cost of 11 pen is ₹ $24\frac{3}{4}$

∴ The cost of 1 pen is =

$(24\frac{3}{4}÷11)=(\frac{99}{4}÷11)=(\frac{99}{4×11} )=\frac{9}{4}$

10. 6 Identical articles price is = ₹ $2\frac{6}{17}$

∴ Each articles cost is =

$(2\frac{6}{17}÷6)=(\frac{40}{17}÷6)=(\frac{40}{17×6})=(\frac{20}{51})$

11.The number is =

$(\frac{-9}{16}÷\frac{-3}{8})=(\frac{9}{16}×\frac{8}{3})=\frac{3}{2}$

∴If we multiply (-3/8) by (3/2) the product will be (-9/16).
