Answer 1

$\huge\green{\bold{Hello!!!}}$

$\\ \frac{2}{7} \times \frac{ - 3}{11} - \frac{5}{22} - \frac{3}{11} \times \frac{5}{7} \\ \\ = \frac{ - 6}{77} - \frac{15}{77} - \frac{5}{22} \\ \\ = (\frac{ - 6 + 15}{77} ) - \frac{5}{22} \\ \\ = \frac{9}{77} - \frac{5}{22} \\ \\ = \frac{18 - 35}{154} \\ \\ = \frac{ - 17}{154}$

Hope it helps!!

Hi Mate !!

Here is your answer :

Question : Using Appreciate properties find : 2/7 × ( -3/11 ) - 5/22 - 3/11 × 5 / 7.

Solution :

=> 2/7 × ( -3/11 ) - 5/22 - 3/11 × 5 / 7.

=> ( 2 × -3 ) / ( 7 × 11 ) - 5/22 - ( 3 × 5 ) / ( 11 × 7 ).

=> -6 / 77 - 5/22 - 15 / 77

=> 9/77 - 5 / 22

=> ( 9 × 2 - 5 × 7 ) / 154

=> 18 - 35 / 154

=> -17/154 [ Answer ]
