Answer 2

Answer:

value of given expression ,$\frac{-7}{13} \div\frac{35}{-39}$  is $\frac{3}{5}$ .

Step-by-step explanation:

To find : value of given expression .

Given : $\frac{-7}{13} \div\frac{35}{-39}$  

Solution :

• To find value of given expression we take reciprocal of second term by changing the sign from division to multiplication .
• Hence , we write $\frac{-7}{13} \div\frac{35}{-39}$   as $(\frac{-7}{13})\times( \frac{-39}{35})$ .
• We know that according to integer law of multiplication , if two negative integers are multiplied then the product obtained is positive integer. i.e. $(-) \times(-)=+$ .

• Therefore , solving $(\frac{-7}{13})\times( \frac{-39}{35})$ according to above law .

         $(\frac{-7}{13})\times( \frac{-39}{35})\\\\= \frac{-1}{1} \times \frac{-3}{5} \\\\=\frac{3}{5}$
