Question

5/9 : ( 1/11 - 5/22 ) + 5/9 : ( 1/15 - 2/3 ) = ?

Answer 1

\(\frac{5}{9}:\left(\frac{1}{11}-\frac{5}{22}\right)+\frac{5}{9}:\left(\frac{1}{15}-\frac{2}{3}\right)=\frac{5}{9}:-\frac{3}{22}+\frac{5}{9}:-\frac{3}{5}=-\frac{110}{27}+-\frac{25}{27}=-5\)

Answer 2

5/9 : (2/22 -5/22) + 5/9 : (1/15 -10/15)

=5/9 : -3/22+5/9: -3/5

= -110/27+ -25/27

=   -5
