$\huge\color{purple}{αղ}\purple{sա}\pink{ҽɾ}\color{pink}{☘}$

$\\ 1)3 \div \frac{1}{2}$

$\\ \implies \frac{3}{1} \times \frac{2}{1} = \bold{6}$

$\\ 2)3 \div \frac{ - 3}{7}$

$\\ \implies \frac{ \cancel{3}}{1} \times \frac{ - 7}{ \cancel{3}} = \bold{ - 7}$

$\\ 3) \frac{ - 5}{4} \div \frac{8}{ - 15}$

$\\ \implies \frac{ - 5}{4} \times \frac{ - 15}{8}$

$\\ \implies \frac{75}{32}$

$\\ 4) \frac{ - 7}{8} \div \frac{ - 21}{16}$

$\\ \implies \frac{ - 7}{8} \times \frac{ - 16}{21}$

$\\ \implies \frac{2}{3}$

$\\ 5) \frac{2}{3} \div \frac{ - 7}{12}$

$\\ \implies \frac{2}{ 3} \times \frac{ - 12}{7}$

$\\ \implies \frac{ - 8}{7}$

Answer 2

Step-by-step explanation:

Divide :

(¡). 3 by 1/2

= 3÷1/2

= 3×2

=6

Divide 3 by 1/2 = 6

(¡¡). 3by -3/7

= 3÷-3/7

=3×-7/3

= -7

Divide 3 by -3/7 = -7

(¡¡¡). -5/4 by 8/-15

= -5/4÷8/-15

= -5/4×-15/8

= 75/32

Divide -5/4 by 8/-15 = 125/32

(iv) . -7/8 by -21/16

= -7/8÷-21/16

= -7/8×-16/21

=2/3

Divide 7/8 by -21/16= 2/3

(v). 2/3 by -7/12

= 2/3÷-7/12

= 2/3×-12/7

= -8/7

Divide 2/3 by -7/12= -8/7
