\(\left(-\frac{15}{22}\div-\frac{5}{11}\right)\cdot\frac{2}{3}\)
\(=\left(-\frac{15}{22}\cdot-\frac{11}{5}\right)\cdot\frac{2}{3}\)
\(=-\frac{3}{2}\cdot\frac{2}{3}\)
\(=-1\)
(-15/22: -5/11). 2/3
= ( -15 /22 x -11 / 5 ) x 2/3
= 3/2 x 2/3
= 6/6
= 1
(-15/22: -5/11).2/3
= ( -15/22 . -11/5).2/3
= 3/2 . 2/3
= 1
= (-15/22 . 11/-5) . 2/3
= 3.1
----- .2/3 =3/4 . 2/3 =9/8
2.2
