Question

pls answer with method​

Answer 1

Given:

Solution of Q (i):

$\frac{7}{24} - \frac{17}{36} \\ \frac{21 - 34}{72} \\ \frac{ - 13}{72}$

Given:

Solution of Q (ii):

$\frac{ - 3}{8} - \frac{7}{11} \\ \frac{ - 33 - 56}{88} \\ \frac{ - 89}{88}$

Given:

Solution of Q (iii):

$\frac{5}{63} - \frac{ - 6}{21} \\ \frac{5}{63} + \frac{6}{21} \\ \frac{5 + 18}{63} \\ \frac{23}{63}$

Given:

Solution of Q (iv):

$\frac{ - 6}{13} - (\frac{ - 7}{15} ) \\ \frac{ - 6}{13} + \frac{7}{15} \\ \frac{6 \times 15 + 7 \times 13}{195} \\ \frac{1}{195}$

Given:

Solution of Q (v):

$- 2 \times \frac{1}{9} - 6 \\ \frac{ - 19}{9} - 6 \\ \frac{ - 19 - 54}{9} \\ \frac{ - 73}{9}$

Answer 2

$\underline{\huge \sf \red☯ \purple{Answer:}}$

Solution 1.)

$\frac{7}{24} - \frac{17}{36} \\ \\ ➩\frac{21 - 34}{72} \\ \\ \!\!\! \!\!\!\!\!\!➩\frac{ - 13}{72}$

Solution 2.)

$\frac{5}{63} - ( \frac{ - 6}{21} ) \\ \\ ➩\frac{5}{63} + \frac{6}{21} \\ \\ \!\!\!\!\!➩\frac{5 + 18}{63} \\ \\ \!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!➩\frac{23}{63}$

Solution 3.)

$\frac{ - 6}{13} - ( \frac{ - 7}{15} ) \\ \\ ➩\frac{ - 6}{13} + \frac{7}{15} \\ \\ ➩\frac{ - 90 + 91}{195} \\ \\ \!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!\!➩\frac{1}{195}$

Solution 4.)

$\frac{ - 3}{8} - \frac{7}{11} \\ \\ ➩\frac{ - 33 - 56}{88} \\ \\ \!\!\!\!\!\!\!\!\!\!\!\!\!\!\!➩\frac{ - 89}{88}$

Solution 5.)

$- 2 \frac{1}{9} - 6 \\ \\\!\!\! ➩ \frac{ - 19}{9} - 6 \\ \\ ➩ \frac{ - 19 - 54}{9} \\ \\\!\!\!\!\!\! \!\!\!\!\!\!\!\!\!\! ➩\frac{ - 73}{9}$
